What is a molecule atom What is a molecule and what is an atom.

First of all, oxygen and nitrogen are two substances, or a large number of molecules together; The oxygen molecule is composed of two oxygen atoms, and the nitrogen molecule is composed of two single atoms; But noble gases can be said to be made up of atoms, because one of their atoms is one of their molecules.

Sucrose is also a substance, and it is not monoatomic, so it is also made up of molecules, a sucrose molecule is made up of 12 carbon atoms, 20 hydrogen atoms, and 10 oxygen atoms.

It is the smallest particle that exists independently and maintains the materialized nature of the hidden megagram.

Molecules have a certain size and mass; There is a certain interval between molecules; Molecules are in constant motion; There is a certain force between molecules; Molecules can be made up of matter, and molecules, in chemical changes, can also be divided into smaller particles: atoms. Molecules can be converted into each other in the 3 states with the change of temperature.

The properties of the same kind of molecule are the same, and the properties of different kinds of molecules are different. The smallest molecule is an isotope of the hydrogen molecule, which is a hydrogen molecule without neutrons, called a molecule with a mass of 1 large, and its relative molecular mass can be as high as several million or more. Molecules with a relative molecular mass of more than several thousand are called polymers.

A molecule refers to the smallest particle that retains the chemical properties of a substance. An atom refers to the smallest particle in a chemical change. An element is a general term for a class of atoms that have the same number of nuclear charges, i.e., the number of protons in the nucleus.

A substance made up of molecules, which are the smallest particles that maintain the chemical properties of a substance. Atoms are the smallest particles in chemical change. Molecules and atoms are both particles that make up matter, very small in mass and volume, separated from each other, constantly moving, both of which are different in type and number, and are not electrically significant.

The molecules are always in constant motion, and there are gaps between the molecules.

The simplest of all atoms is a hydrogen atom that contains only one electron, while a complex atom can contain hundreds of electrons. Electrons are distributed in the space around the nucleus like clouds (electron clouds) because they are distributed by chance, so the electron clouds have different shapes and directions of extension. A molecule is a combination of atoms.

Atoms are the smallest particles that make up matter. No, atoms can be divided into nuclei and extranuclear electrons, which in turn are composed of protons and neutrons, and the number of protons is the basis for distinguishing various different elements. Protons and neutrons can continue to be divided.

So atoms are not the smallest particles that make up matter, but atoms are the smallest particles in chemical reactions.

Molecule: The smallest particle that can be broken down in a chemical change.

A molecule is a type of particle that makes up matter; Molecules determine the chemical properties of substances (composed of molecules), the same molecules, the properties are the same, and the properties of different kinds of molecules are not the same; In addition to molecules, there are other particles that maintain the chemical properties of the substance;

Atom: The smallest particle in chemical change (in physics, an atom is composed of the nucleus and electrons outside the nucleus) (1).It is the smallest particle in chemical change and is a microscopic concept (2).

Atoms make up molecules and can also directly form matter. （3）.Atomism can say both a certain atom and a certain atom.

Atoms are composed of chemical bonds (chemical bonds, covalent bonds, metal bonds) and hydrogen bonds, and atoms are the building blocks of all 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 (composed of protons, neutrons, etc.) 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.
