When an electron "jumps" into a higher orbital, then it becomes "excited". So, you can identify electrons in excited state when there is electronic transition from a lower orbital to a higher one. For example in Carbon:

Normal Electronic Configuration: [He] #2s^2 2p^2#
Excited State: [He] #2s^1 2p^3#

See how the electron in the s orbital jump to the p orbital?
