Study Notes
- Lithium does not form peroxide or superoxide.
- Lithium ion has high polarizing power due to its small size.
- Lithium peroxide and lithium superoxide do not exist.
- Majority of alkali metal salts are anhydrous.
- Lithium and sodium salts are most likely to exist as hydrated salts.
- Lithium has an unusually large hydration energy.
- Lithium ion is hard to reduce but easy to oxidize.
- The small size of the Li+ ion allows a close approach to surrounding water molecules.
- Lithium has the highest first ionization energy.
- Oxidation to produce Li+(aq) is different from ionization energy.
