(1) both form highly refractory oxides with polymorphs
(2) both form crystalline nitrides that are hydrolysed in water
(3) addition of hydroxide ion to solutions of the salts gives an amphoteric hydroxide, which is soluble in excess hydroxide giving beryllate or aluminate ions [Be(OH)4]2− and [Al(OH)4]−
(4) both form covalent halides and covalent alkyl compounds that display bridging structures
(5)both metals dissolve in alkalis.
