Part b solid lithium metal and diatomic nitrogen gas react spontaneously to form a solid product. give the balanced chemical equation (including phases) that describes this reaction. indicate the phases using abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively.

Lithium metal which is an alkali metal belongs to the Group I of the periodic table reacts spontaneously with nitrogen, (which remains in gaseous form at room temperature) to form solid lithium nitride (). The reaction can be shown as- 6Li (s) + (g) = (s). This is the only example of alkali nitride in chemistry. The other alkali nitrides are either not stable or does not exist in solid form at room temperature.
