Ground state energy in Optical Spectroscopy & Atomic Structure

Homework Statement

I just want to know if there is a relationship between the ground state of Hydrogen which is 13.6 eV and the ground state of Helium. The problem is asking me to find the ground state of Helium, but I am not sure how to go about it. Any advice?

The Attempt at a Solution

 

[Redbelly98]

It is not possible to find an exact solution for the ground (or any other) state in neutral helium atoms. Only numerical approximations are possible.

However, if the problem is actually asking to find the ground state in singly-ionized helium, He⁺, an exact solution is possible. Can you clarify what the problem is really asking for?
