Naming of Binary Ionic Compound with (Type II) metals
Systematic Name (IUPAC)
Common Name

FeN
SnO
CrCl
CuP
PbS
- Iron[III] Nitride

How do you name Type II metals In Systematic name (IUPAC) AND in Common Name(Old name)

Systematic (IUPAC) name- Metal [Roman # indication charge] + Base name of anion ending with ide

Common Name(Old name)= Metal with the higher charge ends with 'ic'

Lower Charge- Metal with Smaller charge end with 'ous'

What are molecular Compounds?
- Molecular Compound exist as a molecule
- Molecular Compound consist of only nonmetallic elements grouped together
- DO NOT HAVE IONS
