Group 13 elements show less tendency to form ionic compounds than do group 1 and 2 elements, which primarily form ionic compounds because

Options

A. they are p-block elements
B. they fall after d-block elements
C. the loss of successive electrons from an atom requires increasingly more energy
D. none of these

Answer

C

Explanation

Boron forms no compounds with `B^(3+)` ions. The bonding is normally convalent. However, the tendency to form ions becomes greater goind down any column of the periodic table because of decreasing `Delta_iH`. The reamining elements of group 13 do form compounds containing `3+` ions
