    A molecule is the smallest particle that can exist on its own and maintain the chemical properties of a pure substance. A molecule is an electrically neutral particle that is bonded by multiple atoms bonded to each other by covalent bonds[1][2]. In the abstract, a single atom can also be thought of as a molecule (monoatomic molecule), but in practice, "molecule" usually refers to a chemical compound with multiple atoms.

    A substance that is made up of molecules is called a molecular compound.

    The concept of molecule was first proposed by Amodeo Avogadro of Italy, who published the molecular theory in 1811, arguing that "an atom is the smallest particle point that participates in a chemical reaction, and a molecule is the smallest particle point that a single substance or compound can exist independently in the free state." Molecules are made up of atoms, elemental molecules are made up of atoms of the same element, and compound molecules are made up of atoms of different elements.

    The essence of chemical change is the recombination of various atoms in the molecules of different substances. ”

    A molecule is formed by multiple atoms linked together by shared electrons in a covalent bond. It can be made up of atoms of the same chemical element, like oxygen O2; It can also be different elements like water molecule H2O. In the abstract, a single atom can also be thought of as a molecule (monoatomic molecule), but in practice, "molecule" usually refers to a chemical compound with multiple atoms.

    In thermodynamics, the molecules (such as water), atoms (such as gold), and ions (such as sodium chloride) that make up matter all exhibit the same properties in thermodynamics, so they are all collectively referred to as molecules.

    A molecule is a tiny unit that makes up a substance, and it is a small particle that can exist independently and maintain all the original chemical properties of the substance. Molecules are generally made up of smaller particles – atoms. According to the number of atoms that make up the molecule, it can be divided into monoatomic molecules, diatomic molecules and polyatomic molecules; According to the electrical structure, it can be divided into polar molecules and non-polar molecules The microstructure and shape of the molecules of different substances are different, and the ideal model of the molecule is to regard it as spherical, and its diameter is of the order of 10 (-10) m.

    The order of magnitude of the molecular mass is about 10 (-26)kg.

    So it's not an animal.

    Of course not, molecules, atoms, and ions make up all kinds of substances in the world, not just animals.

    The reason why living things are made up is that they have biological characteristics, and the molecules with biological characteristics are mainly chiral, that is, optical rotation, to complete various life activities.

    PS: Understand it yourself, not necessarily correct.

    The cells of animals do not have a cell wall and chloroplasts, whereas plants do, plants move and leave the ground without a hair, whereas animals can. Animals have teeth and body hair, while plants do not, animals absorb oxygen and release carbon dioxide, while rising and withering plants absorb carbon dioxide and release oxygen from noisy grinding holes. That's the difference.

    Chemical bonds are formed between molecules due to intermolecular forces, and generally speaking, chemical bonds are not easy to break. Because once a certain distance between molecules is exceeded, the gravitational force between the molecules will attract each other, and once it is less than this distance, it will be manifested as repulsive force repelling each other. Moreover, the strength of the intermolecular force is at least ten times greater than that of gravitational force.

    First of all, your statement is wrong, people and animals are composed of countless cells, only inanimate objects are made of molecules, and an object becomes two objects by the influence of an external force, then its original molecular structure has changed, and there is no such thing as breaking.

    When the molecule breaks, a chemical reaction occurs.
