Explain why is there a phenomenal decrease in ionisation enthalpy from carbon to silicion.

Solution

This is a due increase in atomic size and screening effect because of which the force of attraction of the nucleus for the valence electron decreases considerably in Si as compared to C. As a result, there is a phenomenal decrease in ionisation enthalpy from carbon to silicon.
