(which is made of Protons, Neutrons, and Electrons) Pure hydrogen is made of atoms. A stable hydrogen atom has 1 proton, 1 neutron, and 1 electron. Protons and Neutrons can be broken down further into Quarks, Leptons, and Bosons. The Electron is a type of Lepton.

How is a molecule different than a compound?
A molecule is two or more atoms held together by covalent chemical bonds. A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds
