Iron (II) SulfIDE\n\nSodium ChlorIDE\n\nSodium HydroxIDE\n\nand Lead...umm...something. *lol*\n\nThe answer is evidently (A). =D\n\n\n\nPS okay, so yea, someone already wrote what i wrote when i was typing it. sorry!

a) sulfur tetrafluoride\nb) molybdenum tetrachloride\nc) cobaltous sulfide or cobalt sulfide\nd) SnO\ne) ferric chloride\nf) CrO3\n\nComment: the above names are the ones you're most likely to encounter in industry or in a real-world laboratory.  Few chemists out here would call FeCl3 "iron three chloride"!\n\nOh, I know, your teacher probably expects "sulfur (IV) fluoride, molybdenum (IV) chloride, cobalt (II) sulfide, and iron (III) chloride..."

Some of the matals have multiple oxidation states and these must be indicated in the names:\nAmericurium (III) fluoride\nIndium (III) fluoride\nBarium permanganate\nNeodymium (III) iodide\nCadmium sulfite\nSilicon tetrathiocyanate\nVanadium (III) fluoride\nIron (III) dichromate\nGold (I) cyanide\nBarium bromate\nMagnesium molybdate\nPlutonium (III) bromide\nSamarium (III) sulfate\nTungsten (II) iodide\nPotassium borate

Yes, they do. The simplest example I can do is Fe (iron): it's a transition metal and has 3 oxidation states: 0 (Fe as a metal), +2 (FeO), and +\n3 (Fe2O3).

The position of the elements in the periodic table gives you clues about the valences of each element. Also, if you remember the formulae for familiar substances (like carbon dioxide, water, sulfur dioxide, hydrochloric acid, etc) that will also give you clues about possible or likely valences. \n\nThe final answer is:\n\nmemorize.

google it and type 'periodic table, first twenty elements'\nn u'll get sumthing, far quicker than lettin sum1 write them up 4 u.
