Naming Compounds

I have to find the names of these compunds

FeCl2 - Iron Dichloride
TiCl4 - Titanuim Tetrachloride
CoS - Cobalt Sulfide
FeBr3 - Iron(III) Tribromide
NaNO2 - Sodium Nitrate
Li3PO4 - Lithium Phosphate
ICl3 - Iodine Trichloride
Pl3 - ?
SO2 - Sulfide

Are these right?

first one is Iron (II) chloride

FeCl2 - iron (II) dichloride or ferrous chloride
TiCl4 - titanium tetrachloride
CoS - cobalt (II) sulfide or cobaltic sulfide
FeBr3 - iron(III) tribromide or ferric bromide
NaNO2 - sodium nitrate
Li3PO4 - trilithium phosphate
ICl3 - iodine trichloride
Pl3 - phosphorus triiodide
SO2 - sulfur dioxide or sulfur (IV) oxide or sulfurous oxide

Isnt it just Iron(II) Chloride? I thought the prefix method for naming compounds was only for covalently bonded compounds... Might be wrong though

[color=darkgreen]Same here, though I've seen Na3PO4 as both sodium phosphate and trisodium phosphate. My guess with that kind of nomenclature is that there is such a large difference in the charges (+1 and -3), so it's possible that such a molecule behaves more covalently.

And, I hate to correct all of you, but NaNO3 is sodium nitrate. NaNO[b]2[/b] is sodium [b]nitrite[/b].[/color]
