Rules for Naming CompoundsFormula begins with a metal Formula does NOT begin with a metal

‘H’ in front NO ‘H’ in front

1)Metal name *

2) Polyatomic name

1) Metal name *

2) Non metal ROOT + IDE

Only 2 elements More than 2 elements

1) Name 1st element

2) 2nd element ROOT + IDE

3) Prefix needed for subscripts

(di, tri, tetra, penta, hexa, hepta, octa, nona, deca)

Only 2 elements More than 2 elements

1) Write HYDRO

2) 2nd element ROOT + IC

3) Write ACID

Polyatomic ends with ATE

Polyatomic ends with ITE

1) Polyatomic ROOT + IC

2) Write ACID

1)Polyatomic ROOT + OUS

2)Write ACID

Classic Names: add –OUS for lower charge/ -IC for higher charge to these roots

(NH4+ acts like a metal)
