Question

21. The highest first sonization energy of the following
elements is that of
a) C
(b) a
(c) 1
(d)li​

Answer 1

Answer:

Carbon has the highest first ionization energy.

The order of the ionization energies is Li<Be<B<C

On moving from left t right in a period, the ionization energy increases as the effective nuclear charge increases and the size decreases. The removal of electron becomes more and more difficult.
