NO3-

Nitrate (Polyatomic ion. Ions that are composed of many atoms. Ate has 1 more oxygen than ite)

NO2-

Nitrite (Polyatomic ion. Ions that are composed of many atoms)

N3-

Nitride (Monoatomic ion. An ion thats composed of one particle one atom) usually lacks oxygen

Polyatomic (ate or ite)

When you have a Polyatomic ion thats has ate or ite it always has oxygen

SO4^2-

Sulfate (Polyatomic)

SO3^2-

Sulfite (bc ate has 1 more than ite)

Phosphide

Cl-

Chloride

ClO-

Hypochlorite

Ide and Hypo

If there is something infront of ide it adds hypo in front and the end changes to ite

ClO2-

Chlorite

ClO3-

Chlorate

ClO4-

Perchlorate

Ate and per

If something has one more oxygen than ate then you add a per infront
