Which of the elements listed below has the smallest first ionization energy?

a) C

b) Ge

c) P

d) O

e) Se

Expert Solution

14th group 15th group 16th group

C N O

Si P S

Ge As Se

In groups from top to bottom ionisation energy decreases

and in periods from left to right ionisation energy increases.

So in the given options "Ge" is having smallest first ionisation energy
