(24 cards)
Monatomic Cations
- Na = Sodium
- Ca = Calcium
- Al = Aluminum
Na +

Transition Metals
Two ways to name:
- Fe 2+ = Ferrous or Iron (II)
- Fe 3+ = Ferric or Iron (III)
- Cu+ = Cuprous or Copper (I)
- Cu 2+= Cupric or Copper (II)

Monoatomic Anions- change the element ending to “-ide”
- Cl = Chlorine, Cl - = Chloride, Charge of Group 17 anions: -1
- O = Oxygen, O 2- = Oxide, Charge of Group 16 anions: -2
- N = Nitrogen, N 3- = Nitride, Charge of Group 15 anions: -3
Cl = ?, Cl - = ?, Charge of Group 17 anions: ?
Cl = Chlorine
Cl - = Chloride
Charge of Group 17 anions: -1
O = ?, O 2- = ?, Charge of Group 16 anions: ?
O = Oxygen
O 2- = Oxide
Charge of Group 16 anions: -2
N = ?, N 3- = ?, Charge of Group 15 anions: ?
N = Nitrogen
N 3- = Nitride
Charge of Group 15 anions: -3
Four Polyatomic anions ending in “-ide”
- Hydroxide = OH -1
- Cyanide = CN -1
- Peroxide = O2 2-
- Azide = N3 -1
Hydroxide
OH -1

Oxyanions ending in “-ate”
-1 Charge:
- Acetate = C2H3O2 -1 or CH3COO-1
- Chlorate = ClO3 -1
- Nitrate = NO3 -1
- Permanganate = MnO4 -1
-2 Charge:
