Some compounds are composed of nonmetal atoms bonded
together to form an ionic compounds or polyatomic ions. 15 Two Routes to Form Compounds Different # protons=
Different elements Atomic Element (AE), Molecular Element (ME),
Molecular Compound (MC), or Ionic Compound (IC) Nonmetal atoms

Compounds Predicting Ionic Charge with Periodic Table
(memorize these) Ag+ Compounds must be neutral (charge=0), therefore the numbers of
cations and anions in a compound must balance to get 0 charge. Classify each of the following as: Electrons + Neutrons + Protons
Atoms with examples: nitrate- NO3- , sulfate- SO42- ,p...
