What is the most fundamental unit of matter?

Explanation:
Matter is built from atoms—the smallest unit that retains the properties of an element. An atom's identity is set by the number of protons in its nucleus, and it includes smaller particles like electrons and a nucleus of protons and neutrons. Atoms can bond with other atoms to form molecules, which are simply groups of two or more atoms held together. When those atoms are the same element, you get a molecule of that element (like O2); when they are different elements, you have a compound (like H2O). So, the atom is the fundamental building block of all matter, with molecules and compounds arising from combinations of atoms.
