The atom

• Protons, electrons ,neutrons

Periodic table

Ionic bond metal - nonmetal

Covalent bondSharing of electrons

Nomenclature Naming

• Simple binary

• First element unchanged

• Second element used as prefix with –ide

• Example

• Li2O

• Fist element lithium second element oxygen

• Name lithium oxide

MultivalanceRoman numeral needed• Identify the first element( check if it’s multi

valence):identify the second element

• If the first element is multivalance you need to check which oxidation state will balance the charge on the second element and include it as a roman numeral

• CuCl2 Copper is multivalance

• Cl has an oxidation state of-1 and there is two of them to balance this the one Cu must have an oxidation state of +2

• Answer : copper(II) chloride

polyatomic

Formulas - given names

• Example

• Barium chloride

• Look for barium and chlorine on periodic table –determine their oxidation state

• Ba second column +2

• Cl Seventh column -1 Ba+2Cl-1

• Criss-cross Answer: BaCl2
