How do you calculate the energy required to remove all three electrons from a Li atom? Here is what I have come up with so far.(adsbygoogle = window.adsbygoogle || []).push({});

I know Bohr's formula E_n = -13.6 Z^2/n^2. There is one electron in the outer orbital (n = 2), and two in the inner orbital (n = 1).

E_2 = -13.6*9/4

E_1 = -13.6*9/1

So 2*E_1+E_2 = 20.25*-13.6 = 275.4

Is this correct?

Thanks
