Answer 1

1)Lithium is harder than other alkalis
2)It has high electronegativity
3)It is strongest reducing agent
4)On combustion in air it mainly forms lithium monoxide (Li2O) and lithium nitride (Li3N ) unlike other alkalis.

Answer 2

Difference between lithium and other alkali metals

1. Lithium reacts with nitrogen gas.

  Other alkali metals can't react with nitrogen gas.

2. Lithium cannot form an anion.

   Other alkali metals may form anions.

3. Lithium is the strongest basic alkali metal.

  Other alkali metals have different basicities, unlike lithium.

4. Lithium has the lowest density among the other alkali metals.

   In other alkali metals, the density increases down the group.

5. Lithium has the smallest atomic size of alkali metals.

   the atomic size increases down the group.
