Are there as many elements present on Earth as there are in the universe?

Naturally, there is. Different substances will appear on other celestial bodies that are different from the Earth's environment, and the Earth does not contain everything in the universe

Conventional matter in the universe is composed of various elements, and various elements can be synthesized into various substances in different environments. Not to mention other parts of the universe, substances that do not exist on Earth can also be synthesized in human experiments, for example, various polymer compounds, various synthetic drugs.

If other celestial bodies in the universe had a completely different chemical environment from Earth, there would be material on those celestial bodies that did not exist on Earth. As a special example, electrons degenerate matter. This is the core left by the death of a low- and medium-mass star, due to the strong gravitational collapse effect, the electronic shell around the atom can not bear it and is crushed, and the free electrons and nuclei are tightly squeezed, and together they form a special kind of matter - electron degenerate matter, this material is composed of celestial bodies called white dwarfs.

Due to the tight compression of matter, white dwarfs have an extremely high average density, up to a million times that of water.

As for the elements that make up matter themselves, there may also be elements in the universe that are not found on Earth. Humans have found the first 94 elements in the periodic table on Earth, but there are already 118 known elements, and the other 24 are man-made.

Just like matter, it is also possible for other celestial bodies with different environments to have elements that do not exist on Earth. It is not even possible to rule out elements above number 118, but this is extremely unlikely. Superheavy elements synthesized by humans can only exist for an extremely short period of time, for example, element 116 (LV) has a half-life of only 60 milliseconds.

No, just like matter, it is also possible for other celestial bodies with different environments to have elements that do not exist on Earth.

It's not the same, the universe is too big, and the earth is only a very small part.

It's not the same, the universe is boundless, and we haven't explored it completely.

It's not the same, the universe is very big, and no one dares to say that the universe has been explored.

It's not the same as the universe is very big and it's only a small part of the earth.

No, planets like Jupiter, Saturn, Uranus, Neptune, and Pluto are gaseous or snow-covered planets, while Earth, Mars, Venus, and Mercury are rocky planets.

It's not the same, the universe is so big, and there are so many places I haven't been to.

So far, scientists have not found elements in the universe that are different from the earth.

No one can be sure of this, the universe is very big, and there are many places that no one can reach, so they don't know the factors.

The two most abundant elements in the universe are hydrogen.

and helium elements. Hydrogen and helium are the parent elements of all other elements, without which there would be no more than 100 elements, let alone the beautiful world in which human beings live.

The various elements in the universe are counted by the number of atoms, and hydrogen is the most numerous, accounting for; The second place is helium, occupied; All other elements only account for . In terms of the mass of each element, hydrogen accounts for about 75%, helium accounts for about 24%, and all other elements other than hydrogen and helium account for less than 1%.

We know that all kinds of matter in the universe mainly come from the nuclear fusion reactions in the universe and stars. From the moment the universe was born, the chain of formation of various substances began. There are now more than 90 natural elements on the earth, as well as synthetic elements, adding up to a total of 118 species.

Could this be the total amount of elements in the universe? In the unknown corners of the universe, will there still be chemical elements unknown to mankind? In the eyes of physicists, the probability of the existence of unknown elements is very low.

In nuclear physics, scientists can calculate that there are components in the universe other than known elements, but their chemical properties are very unstable, and the probability of discovering them is very low. The last element of the periodic table, element 118 OG-294, was discovered in 2006 and has a half-life of only seconds, which is an element that exists almost only instantaneously.

Using their own technology, scientists have synthesized 23 elements, from 95 to 118, which is an amazing achievement. But so far, humans have not mastered the method of synthesizing Element 119, because it is only a theoretical thing, and it is very difficult to turn it into reality.

There is a classical "island of stability" theory in physics, which is a conclusion drawn after summarizing the stability of various elements. Scientists have found that if the number of protons and neutrons in a nucleus is one in 126, the atom will exhibit very stable properties. For example, if there are 50 protons of tin in the nucleus, the nucleus is very stable.

However, transuranic elements have a short half-life, and as the atomic number increases, the nucleus becomes more and more unstable. It's getting harder and harder to synthesize or discover it. Scientists propose that when the periodic table develops to element 126, it may be a very stable element, but perhaps the atom will not reach element 126 at all.

In the event of a cosmic event, supernova explosions may form matter larger than Element 118, but their half-lives will be quite short, and they cannot be captured by the current technological means of mankind. What do you think?

The chemical elements on Earth are not all the elements in the universe, they are only a small part of all the elements in the universe.

At this stage, the laboratory can produce elements that will not be in nature, or can not be seen immediately, in addition, everyone can pay attention to the unity of organic matter in the universe, for example, the earth and the whole solar system have the same kind of elements, but the evolution rate of some elements is very different, for example, the earth and the whole solar system have the same kind of elements, but compared with the 94 natural elements on the earth, only some elements have very different evolution rates, Contains hydrogen 1 to plutonium-94.

At this stage, it is already known that the total number of elements has reached 118, and the other 24 elements are synthetic, and if the synthetic elements are removed, then the organic chemical elements that cannot be used on the earth are very likely to exist on other planets in the universe. As everyone knows, the evolution rate of high uranium elements on other planets should be very high, and the types of elements contained in them are not easy to be very different from those of the earth.

According to the canonical model of the universe, the origin of the universe can be traced back to the endless singularities of 13.8 billion light years ago. In the gradual development of the universe, there are no chemicals as we know them today, and there is no indoor space. About 10 seconds after the universe came out, it quickly cooled out after the universe bloomed, and the universe began the whole process of nucleosynthesis in Taihu for more than ten minutes, during which protons, hydrogen nuclei and neutrons were slowly produced, and protons and neutrons combined into helium nuclei.

Because of the further expansion and refrigeration of the universe, the relative density and humidity plummeted, and there was no standard nuclear fusion reaction in the universe, although the nuclear synthesis of Hongmeng only lasted for ten minutes, but this whole process caused all the material conditions of the universe today, because of the proportion of light quantum and baryon, the quality of hydrogen synthesized in the universe accounted for nearly 75, the quality of helium accounted for nearly 25, and there were also very small amounts of beryllium and lithium, about 100 million light years after the universe came out, hydrogen and helium clouds combined to produce the first planet in the universe that completely cooled the universe.

The difficult question of whether the organic chemical elements on Earth are all the elements in the universe is expressed here today.

Of course not. Because the chemical elements on the earth are only a small part, now our country's science and technology are particularly developed, and we can create new elements by ourselves.

No, because the universe is very large, there are all kinds of matter in the universe, and only 50% of the matter on the earth is there.

In the development of human chemistry, there are very few chemists who can go down in history. The exception was Mendeleev, the founder of the chemical element table, and anyone who aspired to work in chemistry had to bow down in front of Mendeleev's podium. In the eyes of a chemical dog, a list of chemical elements is the whole world.

Let's think about whether the elements of the entire universe are gathered in the chemical element table. In other words, all the elements in the universe are on Earth, in the hands of human beings? Of course it is no.

In the eyes of experts in basic theory, the use value of the elements is the same as that of the creator. If you discover a new element, this year's Nobel Prize in Chemistry will be yours by no surprise.

This is the value of discovering the new element, and you have been at this time as the Creator. Even if the element can be produced, a list of chemical elements is obviously not enough. Mendeleev's list of chemical elements has been almost perfect.

It can even analyze the parts of unknown elements and inspire everyone to feel with their hearts. But the quest for chemical production of new elements is never-ending. People have already produced more than a dozen elements by manpower, and the list of chemical chemical elements of 118 elements is nothing more than everything in the universe that people understand.

Under human observation, the entire universe seems to stop there, with only 118 elements, neutron star mergers and supernova explosions, which are the heavy element production factories of the universe. It is even believed that there are only 98 elements in the universe, and that the elements that people can generate cannot be generated in the universe.

If star orbits are affected by supernova explosions of massive stars, then the stars formed from these orbits will have the same types of elements as on Earth, with only a few differences in content. Naturally, other planets do contain a very small number of elements that are not found on Earth, and the content of such elements should be extremely low. In addition, it is unlikely that there will be particularly high mass primors on other planets, and because transuranic primors are very unstable, they are very susceptible to nuclear decay into more stable and lighter molecules.

Because of this, the elements created on 94 can generally only be stored for a short period of time. In addition to ordinary chemicals composed of various elements, there is also dark energy in the universe that has not been understood until now. Based on observations, it is inferred that dark energy is much larger than that of ordinary chemicals, and that they are no longer composed of chemical elements as we know them.

No. Because the chemical elements on the earth are very limited, and the universe is very large, and there are many unknown elements, the chemical elements on the earth are not all the elements in the universe.

The chemical elements on the basis of point 1 must be all the elements in the universe, because they are the whole elements, and they have a cosmic transformation, and this speed can reach a standard.

I don't think it's all the elements in the universe, after all, the universe is infinite, we have only explored a small part of it, and there are still a lot of unknowns.

All the elements in the universe are made up of elementary particles such as protons, neutrons, and electrons. The number of protons in the nucleus determines the type of element. For example, if there is only one proton in the nucleus, it is hydrogen, and if there are two protons, it is helium.

In practice, this is very difficult. Because protons are positively charged, it is very difficult to hold them together and requires very high temperatures and pressures. Let's take a look at how the universe does it.

The early universe was not as colorful as it is today, and space at that time was filled with a lot of elementary particles. Hydrogen gas with only one proton in the nucleus is easily formed, and as the temperature of the universe gradually decreases, the universe is flooded with hydrogen, forming a primitive nebula. It slowly multiplies into a primordial star under the pull of gravity, and at the same time, the pressure and temperature of its core gradually increase due to the increase in its gravitational pull.

In this case, the nuclei of light elements will capture a large number of neutrons in a very short time, but these neutron-rich nuclei are extremely unstable, and they will quickly decay and thus transform into stable, heavier nuclei than iron elements, which is fast neutron capture.

When the mass of the primordial star reaches a certain point, the temperature and pressure of the core are high enough for the protons to fuse together, and new elements are created, while a large amount of energy is released in the process, which is known as nuclear fusion. During this time, clumps of light elements were drawn together to form early stars. When the accumulation of light elements is large enough, the core of the star will undergo light nuclear fusion under the influence of gravity, turning hydrogen into helium, and in the process producing a huge amount of energy, releasing a searing glow into interstellar space.
