Polyatomic Ions Flashcards
These are covalently bonded structures w/ a charge
Whenever they’re in a molecule we automatically know its an ionic compound

Dichromate
Dice are lucky 7
Di = 2 and 2 is in it twice
Dichromate
ammonium
* special its the only cation polyatomic ion
Ammonium
Cyanide
Cyanide
Hypochlorite

Chlorite
Chlorite
Chlorate
Chlorate
Perchlorate
Perchlorate
These are talking about the amount of oxygen
Per
Ate
Ite
Hypo
These are the order they come in. I think ate is typically the base unit
Cl, Br, I all have 4 varients of polyatomic ions (they’re also all in the same group coming one after the next in the periodic table)
