Solution

The correct option is A $B i$
$C a$ is most metallic since it belongs to II group and Sulphur is most non-metallic since it belongs to 16 group. $B i$ lies in 15 group and hence it will have intermediate value for first ionization.

With reference only to the periodic table, indicate which of the atoms Bi,S,Ba,As and Ca has the intermediate value when the five are arranged in order of increasing first ionisation energy.

The correct option is A BiCa is most metallic since it belongs to II group and Sulphur is most non-metallic since it belongs to 16 group. Bi lies in 15 group and hence it will have intermediate value for first ionization.
