Question

max ionization energy for a) Li b) Be c) N d)F

Answer 1

Answer:

Max. Ionisation Energy will be find in

Beryllium ( Be )

Explanation:

★ Because the Electronic configuration of beryllium is

1 s² , 2 s²

so ; to remove electron from fully filled orbital is very hard than that of half filled orbital.

Answer 2

Answer: Option b is correct

Explanation:

The third I.E. amongst Li,Be,B and C is lowest for B.

Because after removing the two electron its electronic configuration Have become 1s

2

,2s

1

.

After removing this electron from 2s orbital it will attain the stable electronic configuration of helium hence the third ionization energy of boron is lowest.
