| Question | Answer |
|---|---|
| CrO4 -2 | Chromate |
| CO3 (-2) | Carbonate |
| NO3 (-1) | Nitrate |
| OH (-1) | Hydroxide |
| NH4 (1) | Ammonium |
| CN (-1) | Cyanide |
| SO4 (-2) | Sulfate |
| PO4 (-3) | Phosphate |
| Ionic Bonds | formed with single element ions, strong because electrons are donated/given up, formed between a metal and a non-metal |
| Covalent Bonds | Formed with multi element ions, share electrons which make the bond weaker, formed between two non-metals |
| Monoatomic Ions | Made up of one element, formed with ionic bonds (donate electrons), strong because they have opposite charges that attract each other |
| Polyatomic ions | Made up of two or more elements, names never change name!!, covalent bonds (share electrons) |
| Transition Metals | Always cations, ionic bonds, charge based on oxidation level, use Roman numerals |
| cations vs anions, which comes first | cations then anions |
