@ -156,6 +156,11 @@ are all mono-valent. (not multi-valent)

|Monohydrogen phosphate ion|$`HPO_4^{2-}`$| |Monohydrogen phosphate ion|$`HPO_4^{2-}`$|
- For above, we use mono for phosphate to avoid ambigious cases, where $`H_2PO_4^{-}`$ and $`H_2PO_4^{2-}`$ are the same if we don't put `mono` infront. As for the Hyrogen carbonate ion
we don't put a mono due to no ambigious cases.
## Molecular Compounds
- Are not made of ions, instead molecules
- Shared pairof electrons -> `covalent bonds`
