One mole of magnesium nitride on the reaction with an excess of water gives
one mole of ammonia

Beryllium and aluminium exhibit many properties which are similar. But, the two elements differ in
exhibiting maximum covalency in compounds
forming polymeric hydrides
forming covalent halides
exhibiting amphoteric nature in their oxides.
Among the properties reducing oxidising complexing, the set of properties shown by ion towards metal species is
