Naming compounds

Ionic Compound

1 metal + 1 nonmetal 

ALWAYS balance charges (= 0).

Molecular (covalent) Compound

2 nonmetals

DO NOT balance charges

Column 1, 2, 13 charges

+1, +2, +3

Column 14, 15, 16, 17 charges

±4, -3, -2, -1

Ionic compound w/ polyatomic atom

• name of metal 

• Polyatomic atom

Ionic compound w/ trans. metal & polyatomic atom

• Name or trans. metal

• Roman numeral

Naming acids

• acid = hydrogen in front.

• Hydro( )ic acid

• Hydro = no oxygen

• ( )ous acid

• Has oxygen

• Polyatomic atoms:

• -ous = -ite

• -ic = -ate

• I ATE organIC apples despITE being poisonOUS

Naming acids from chem. form.

Ex) HF

1. Hydro bc no Oxygen

2. Hydro( )ic acid —> hydrofluoric acid
