Excitation of an atom

This may be very simple, but I am trying to understand why it is that when an atom is excited it gains energy? Is there an easier visual way for me to understand this?

When an atom becomes excited, an electron in that atom moves to an outer shell (a higher n value). The higher the n value, aka the further away it is from the nucleus, the more energy that electron (and atom) has. Hope this helps!
