Ions-atoms that have gained or lost electrons (negative particles)
Anion: atoms that have gained electrons and have a negative charge
Cation: atoms that have lost electrons and have a positive charge

(Average) Atomic Mass
-isotopes occur in nature in a certain percentage (percent natural abundance) -the atomic mass of an element is a weighted average mass of atoms occurring in nature-see table 4.3
