13.6ev×9=122.4ev .....the ans is (d) 122.4ev....


Tanaya62: can you explain it in detail....????!!!!!
pandeyshristi: Ya ofcourse☺......IE = 13.6Z²/n² eV

Where Z is atomic number and n is the shell number.

In this case Z is 3 and n is 1( because hydrogen is having n=1)

So IE Li²+ = 13.6×9 = 122.4 eV.
pandeyshristi: You are satisfying or not???

pandeyshristi: My pleasure !!!!! yrrr
