Vacuum. Agree with the first answer. Electrons, protons, and neutrons belong to the internal structure of atoms, and of course there are no other molecules or atoms (including air molecules) in the atom
The vacuum is full of fields (such as electromagnetic fields), and the question of whether a field counts as matter is still unclear among scientists.
-
The atom is the smallest unit of chemical change. There are nuclei and electrons in the atom, and the electrons move around the nucleus at high speed, and the nucleus is composed of protons and neutrons, the number of electrons = the number of protons (in the atom) and the electron band"+"point, proton belt"-"Electric, so the whole atom is uncharged.
As for what's inside? I can tell you that there is nothing but electricity! Because matter (including gases and all matter in the world, except for vacuum) is made up of molecules, atoms, or ions.
Molecules, on the other hand, are made up of atoms, and the size of atoms is comparable to that of ions, so there is nothing in the atom except electrons and nuclei!
-
Not necessarily. An atom is a nuclear structure, and electrons move at high speed on its outside, and it is possible that there is some kind of gas in it.
-
There is really nothing there, because we can understand that all matter is made up of molecules or atoms, and the space there is so small that we can't fit any molecules and atoms, but we can't call it a vacuum, and the term vacuum can only be used in the world of macroscopic objects
-
An atom is made up of a nucleus and electrons, and there are also protons and neutrons inside the nucleus.
-
Yes, you should be able to imagine that there are no more molecules of air in that space.
-
The nucleus is made up of protons and neutrons.
Protons and neutrons are made up of quarks.
Electrons move around the nucleus and appear randomly near fixed orbitals.
-
Vacuum. The first reply was completely correct.
However, there may be other substances that have not been discovered that we have not learned.
-
The microcosm cannot be understood in a macroscopic way.
-
It's a cloud of electrons, and electrons move at high speed, forming a cloud, even if it's a single electron.
That space is the space for the movement of electrons, and I think, in the strict sense, in the sense of the size and speed of movement of electrons, it should be a vacuum.
The motion of electrons does not have an orbital, but the energy of electrons is divided into orbitals, and the electrons are arranged according to the orbital energy outside the nucleus.

What kind of story is this? We can see that the atom and molecule in the diagram quarrel and they separate, but the atom meets the other atom. They looked at each other very well, so they started a new family.
This molecule is actually a sulfur molecule, and sulfur is a substance. It has several characteristics: First of all, it is yellowish, so we often see sulfur bogs with a yellowish tinge with a little brown color.
At the same time, it is solid, and the surface bumps are very rough, and it doesn't feel good to the touch. All in all, sulfur is a yellow, rough solid substance.
We did an experiment and the question was this: What happens to sulfur combustion?
The sulfur burned for a while, and then something magical happened - the solid sulfur turned into purple liquid sulfur! The liquid sulphur was put in a small spoon, and after a little more lead trembling, the purple-red liquid sulphur disappeared, and then we smelled a pungent smell, which was the gas from which the sulphur decomposed. Here we can see a process of change in which a solid liquefies into a liquid, and the liquid vaporizes again into a colorless gas.
Sulfur is a substance, and all matter is made up of molecules, that is, sulfur is made up of sulfur molecules. Then the madman is made of atoms, and they decompose, just like the story above. Atoms and molecules disperse to produce a colorless gas, which is what we smell as a pungent odor.
At the same time, after the dispersion stirred sail, the atoms met new atoms, which combined to form a new substance. When a molecule encounters a molecule, it cannot combine and produce a new substance, because the molecule can directly form a substance, and if two molecules are combined, the substance still does not change, which is equivalent to the molecule being this substance. Therefore, after composition, it is no different from the matter megahail itself.
Whereas, atoms make up molecules. They are not matter itself, so they are different from matter. When combined, they become new substances—it's the same story as in this story
The question of the marriage of the atom.

In 897, Thomson discovered the electron in his experiments, and in 1911, Rutherford confirmed the existence of positively charged nuclei by experiments with large-angle elastic scattering of particles. In this way, the existence of atoms and the theory that atoms are made up of electrons and nuclei were experimentally proved.

Atoms are the smallest particles that cannot be redivided in a chemical reaction. A positive atom contains a dense nucleus and a number of electrons that are negatively charged around the nucleus. Whereas, the nucleus of a negative atom is negatively charged, and the surrounding negative electrons are positively charged.
The nucleus of a positive atom is made up of positively charged protons and electrically neutral neutrons. The antiproton in the nucleus of the negative atom becomes negatively charged, thus making the nucleus of the negative atom negatively charged. When the number of protons is the same as the number of electrons, the atom is electrically neutral; Otherwise, it is a positively or negatively charged ion.
Depending on the number of protons and neutrons, the type of atom is different: the number of protons determines which element the atom belongs to, while the number of neutrons determines which isotope the atom is of that element. [3] Atoms make up molecules, and molecules make up substances, in which the same kind of charge repel each other, and different kinds of charges attract each other.
The order of magnitude for the diameter of an atom is about 10-10m. The mass of an atom is extremely small, generally to the power of -27, and the mass is mainly concentrated in protons and neutrons. Electrons are distributed outside the nucleus, and the electron transitions produce a spectrum, which determines the chemical properties of an element and has a great influence on the magnetic properties of the atom.
All atoms with the same number of protons make up the elements, each of which mostly has an unstable isotope that can undergo radioactive decay.
The atom was first an abstract concept with ontological significance in philosophy, and with the progress of human understanding, the atom gradually became a scientific theory from an abstract concept. The nucleus and electrons are microscopic particles that make up atoms. Atoms, in turn, can make up molecules.

Matter in our daily lives is made up of atoms. In the past, atoms were considered elementary particles, and the word atom comes from the ancient Greek word for "indivisible". Later, it was discovered that atoms are composed of positively charged nuclei and negatively charged electrons.
The internal composition of the atom is shown in the following analysis:
The number in the figure represents the smallest unit of indivisible positive and negative electromagnetic information - qubits (Qubit) (name physicist John. Wheeler John Wheeler famously said, "It from bit."
After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

Summary. Pro, atoms are the basic particles that cannot be separated in chemical reactions. What is an atom.
Pro, atoms are the basic particles that cannot be separated in chemical reactions. That is to say, all substances may not be divided again if they are divided by chemical means, and when they are quickly divided into atoms.
An atom is a basic particulate substance that is invisible to the naked eye, well, it can be said that all matter is made up of atoms. An atom is made up of protons and neutrons, where the number of protons of the proto-tumble determines what kind of element this substance really is? When you learn junior high school chemistry, you will find that it is a very interesting, but very difficult knowledge.

1.Imagine a cube with a regular shape, submerged in water, its 6 faces are subject to the pressure of water, because its left and right sides, the front and rear sides of the surface under the water depth is the same, then the pressure of the water is also the same, the pressure is equal in size, the direction is opposite, balanced with each other, and the upper and lower sides are in different depths in the water, the pressure of the water is small, the pressure is also different, the lower surface is subjected to the upward pressure of the water f is greater than the upper surface by the pressure of the water f downward. The net force of the pressure on the object is the buoyant force of the liquid on the object. >>>More
