LITHIUM is least reactive with water AMONG the alkali metals LiCl crystallises from AQUEOUS solution as `LiCl.2H_2O` Lithium is the STRONGEST reducing agent among the alkali metals `LiNO_3` DECOMPOSES on heating to give `LiNO_2 and O_2`.
Solution :`LiNO_3` decomposes on heating to give `LiNO_2 and O_2`.
