the ionization energy of Li2+ is equal to 

  • 9hcR

  • 6hcR

  • 2hcR

  • hcR

Answer

A.

9hcR

Ionization energy is the energy necessary to remove an electron from the neutral atom. 

Ionization energy =  RchZ2 

                         Z = 3 for Li2+

∴  Iionization energy = ( 3 )2 Rch

                                = 9Rch
