Common Cations: Easy to name, usually just the element name. For cations that can have more than one charge, you must specify the charge. Here are 3 common ones you should know:

Fe^2+	iron(II)	Fe^3+	iron (III)
Sn^2+	tin(II)	Sn^4+	tin(IV)
Cu^+	copper(I)	Cu^2+	copper(II)

Common Anions:

Negative ions that consist of a single atom are named by adding the suffix -ide to the stem of the name of the element.

F^-	fluoride	O^2-	oxide
Cl^-	chloride	S^2-	sulfide
Br^-	bromide	N^3-	nitride
I^-	iodide	P^3-	phosphide
H^-	hydride	C^4-	carbide

Common Polyatomic Ions:

HCO3^-	bicarbonate		HSO4^-	hydrogen sulfate (bisulfate)
			ClO4^-	perchlorate
NO3^-	nitrate		ClO3^-	chlorate
NO2^-	nitrite		ClO2^-	chlorite
MnO4^-	permanganate		ClO^-	hypochlorite
CN^-	cyanide		OH^-	hydroxide
		-2 ions
CO3^2-	carbonate		O2^2-	peroxide
SO4^2-	sulfate		CrO4^2-	chromate
SO3^2-	sulfite		Cr2O7^2-	dichromate
			HPO4^2-	hydrogen phosphate
		-3 ions
PO4^3-	phosphate
