Be(Z=4) has maximum covalency of 4 while Al(Z=13) has maximum covalency of 6.

Q. 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

$B e (Z = 4)$ has maximum covalency of 4 while $A l (Z = 13)$ has maximum covalency of 6.
