Question

Which energy state of doubly ionized lithium (Li++) has the same energy as that of the ground state of hydrogen? Given Z for lithium = 3.

Solution

Correct option is

n = 3

. For n = 1 state of hydrogen, we have E1 = C and for the nth state of Li++, we have

For E1 = En, we require  which gives n = 3.
