An atom is the smallest unit of ordinary matter that forms a chemical element. Atoms can attach to other atoms by chemical bonds to form chemical compounds such as molecules. Atoms can also combine to create materials.
The atomic number identifies the number of protons. Atoms can lose or gain electrons. The number of protons in the atomic nucleus determines the number of electrons of the atom in its non-ionized state. A neutral atom has the same number of electrons as protons.
Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. These numbers provide information about the elements and how they will react when combined.
Atoms combine to form molecules, which are the basis of chemistry. All matter, whether it is living or not, is composed of atoms. When different elements undergo chemical reactions, atoms are rearranged into new compounds. An atom is founded on protons, electrons, and neutrons. Therefore, all nature is founded on protons, electrons, and neutrons.
In any atom, like charges repel one another, and opposite charges attract one another. Therefore, two protons repel each other and so do two electrons, but a proton and an electron attract each other. In an element, the numbers of electrons and protons are equal. Moreover, since they have opposite charges, they cancel each other out and keep the atom neutral.
Molecules are simply two or more atoms chemically bonded together. The molecular number is the sum of atomic numbers of all atoms in a molecule. Each type of atom typically forms the same number of bonds. There are many polymorphism types of elements known as allotropy. Isomers are molecules with the same atoms in different geometric arrangements. Because of these different arrangements, isomers often have very different chemical and physical properties.

Classification Tables of Molecular Matter
All matter is composed of elements made of atoms, each with a constant number of protons and electrons. Molecules are made when two or more atoms chemically bond together.
Here you can see the fragment classification table and its transformations in list of molecular formulas.
