Who is the person who made the Elemental Table? Who is the creator of the periodic table?

Mendeleev, but he's just tidying up.

Mendeleev in Russia.

The creator of the periodic table was Mendeleev.

1.The person who came up with the concept of chemical elements was the British scientist Bohr.

In 1661, the English scientist Boyle expressed doubts about Aristotle's four elements and the three originals of the alchemists, and published a pamphlet called "The Skeptic Chemist". Lavoisier's 1789 book Treatise on the Fundamentals of Chemistry listed a list of 33 chemical elements, divided into four categories.

2.Chemical element refers to more than 100 basic metal and non-metal substances in nature, which are composed of only one kind of atom, and each nucleon in its atom has the same number of protons, which cannot be decomposed by ordinary chemical methods, and can constitute all substances.

Some examples of common elements are hydrogen, nitrogen, and carbon. As of 2012, a total of 118 elements have been discovered, 94 of which are found on Earth. Elements with atomic numbers greater than 83 (i.e., after bismuth) are unstable and will undergo radiative decay.

The 43rd and 61st elements, i.e., technetium and promethium, have no stable isotopes and undergo decay. However, even elements with atomic numbers as high as 95 and no stable nuclei can be found in nature, which is the natural decay of uranium and thorium.

The correct answer is d

Chemical elements, a basic concept of chemistry, refers to a collection of atoms of a class with the same number of protons.

The concept of elements sprouted from the four elements of water, earth, fire, and air in ancient Greece and the five elements of metal, wood, water, fire, and earth in ancient China. The concept of elements with a scientific form was developed by the 17th-century English chemist RBoyle proposed.

Macroscopically, he defined an element as a primordial substance or a completely pure substance that is not composed of any other substance, that is, a component of a substance that can no longer be decomposed by ordinary chemical methods. In the 18th century, the French chemist Lavoisier defined an element as "the end point that analysis can reach" and gave what is recognized as the first true table of chemical elements. After the introduction of the atomic and molecular theory, chemical elements were defined as a general term for a class of atoms with the same chemical properties.

Modern physics and chemical research have revealed that the chemical properties of elements are mainly determined by the number of protons (or nuclear charges) in the nucleus, and that the essence of chemical processes is the electromagnetic interaction of electrons outside the nucleus, from which all the chemical phenomena discussed so far arise. Since the nucleus of an atom can be transformed, so can the chemical elements.

When it comes to the periodic table of chemical elements, people's first impression is Mendeleev, he is the inventor of the periodic table of chemical elements, but there are also contributions of us Chinese in the periodic table of chemical elements, he is Zhang Qinglian, he has revised the periodic table of chemical elements ten times, revised the imperfections in the periodic table of chemical elements, let's understand him together.

From 1935 to the present, he has been conducting research on water-focused and stable isotopes, involving isotopes of more than a dozen elements such as hydrogen, oxygen, carbon, nitrogen, lithium, boron, sulfur, indium, antimony, cerium, europium, and iridium. For more than 50 years, systematic and in-depth research has been carried out on the physical and chemical properties of isotope compounds, the kinetic effects of isotopes and the principles and methods of isotope separation, the development of isotope standard samples, the natural abundance of isotopes and the determination of atomic weight, etc., and has published more than 100 articles.

We're ignoring an element that isn't on the element table, people. The most basic element of the world. I've been looking for this ad. Whining.. I can't find it.
