Answer:

Look at the orbitals s,p,d,f.

Explanation:

Basically, the s, p, d, and f orbitals are part of the electron shells, and by looking at the periodic table, one can deduce the spdf configuration (e.g. #"Mg"# has a #1s^2 2s^2 2p^6 3s^2# spdf configuration)

Based on this, the more orbitals it has, the higher the energy level.

Hope this helps!

So, in this case, Mg would have 3 energy levels.
