Beryillum resembles Aluminium in properties. This is mainly due to

Options

A. same values of their electronegativities
B. similar polarising powers of `Be^(2+)` and `Al^(3+)`
C. almost the same values of oxidation potentials
D. all of the above

Answer

D

Explanation

Diagonal relationship and is due to the reason that these pairs of elements have almost identical ionic radii and polarizing power (i.e charge//size ratio).
