Among the elements B, Al, C and Si,

(i) which element has the highest first ionisation enthalpy?

(ii) which element has the most metallic character? Justify your answer in each case.

Answer :

(i) Carbon has the highest ionisation enthalpy as The ionisation enthalpy of elements varies across period and group. The ionisation enthalpy decreases down a group and increases as we move from left to right in a period. It is affected by the following parameters.
