According to Bohr’* theory, the minimum energy required to remove an electron from the ground state of doubly ionized Li atom (Z = 3) is

Question 1

(1) 1.51

(2) 13.6

(3) 40.8

(4) 122.4

Question 2

Correct option : (4) 122.4

Explanation :

According to Bohr’* theory for hydrogen and hydrogen like atoms, the energy in electron volts is given by the relation.

For doubly ionised Li atom z = 3 and it will behave like a hydrogen atom. For ground state. n = 1 and hence we have
