The Attempt at a Solution

I did it using Bohr's expression of energy...Is there any other method to do it?

If you are using Bohr, make sure you account for screening (to determine an effective nuclear charge) using Slater's rules.

More likely, you are required to use Moseley's semi-empirical, somewhat-Bohr-based relationship. Your textbook should cover this.
