HESI A2 Chemistry Acid a compound that is a hydrogen or proton donor. It is corrosive to metals, changes blue litmus paper red, and becomes less acidic when mixed with bases Atom the basic building block of a molecule that contains a nucleus and orbits Atomic mass the average mass of each of that element's isotopes Base a hydrogen or proton acceptor and generally has a hydroxide (OH) group in the makeup of the molecule. Bases are also called alkaline compounds and are subs...
