Problem

Li does not resemble other alkali metals in the following properties: (1)

\text{Li}_2\text{CO}_3

decomposes into oxides, while other alkali-metal carbonates are thermally stable. (2)

\text{LiCl}

is predominantly covalent. (3)

\text{Li}_3\text{N}

is formed when Li metal is heated with

\text{N}_2

gas. (4) All are correct.
