Expert Answer:
The equation of P.E for a one electron atom is
Ep = - Z2e4m
4e02 h2n2
So e- in He+ ion in 4th orbit
Ep = - 22e4m = -me4
4e02 h242 16e02 h2
The equation of K.E for a one electron atom is
Ek = Z2e4m
8e02 h2n2
So e- in Li+3 ion in 3rd orbit
Ek = 32e4m = me4
8e02 h232 8e02 h2
Ep = -me4 x 8 e02 h2 = -1
Ek 16e02 h2 x me4 2
The equation of P.E for a one electron atom is
Ep = - Z2e4m
4e02 h2n2
