Naming Rules

Question 1

Type 1

Answer 1

Ionic compound (metal and non-metal from group 1 or 2 also includes Ag, Zn, Al, and NH4+ which all have set charges)

Metal keeps the name and non-metal changes to an ide ending

Polyatomics stay the same

Question 2

Type 2

Answer 2

Ionic compound (transition metal and non-metal)

Stock name: anion gets ide ending, polyatomic stays the same, metal’s charge is specified by roman numerals

Traditional names:
plumbous (Pb +2)
plumbic (Pb +4)
Ferrous (Fe+2)
Ferric (Fe+3)
Stannous (Sn +2)
Stannic (Sn+4)
Mercurous (HG2 +2)
Mercuric (Hg +2)
Cuprous (Cu +1)
Cupric (Cu +2)

Question 3

Type 3

Answer 3

Covalent Molecules (all non-metals)

Stock names: roman numerals used to show oxidation numbers

Traditional names: use prefixes
(mono, di,tri, etc.) except you don’t use mono for the first element

Question 4

Type 4

Answer 4

Acids, always start with H

oxyacids = if oxygen is present, name of polyatomic ate–> ic and ite–> ous + “acid”

If no oxygen is present it is hydro__ ic acid
