This is not exactly accurate; while atoms are matterâthe smallest pieces of matter you can findâmolecules are the smallest bits of compounds. And particles arenât matter, but the building blocks of it. For example, copper is an element. A copper atom is the smallest piece of copper that exists. Hydrogen is also an element; two hydrogen atoms and one oxygen atom combine to form a molecule of water, which is a compound. While atoms are the tiniest bits of matter, they are made of the sub-atomic building blocks of matterâprotons and electronsârevolving around a nucleus.
