Electron Promotion and Hybridization

[Ashley Lopez 3J]

What is meant when they ask to draw box diagrams to show electron promotion and hybridization? What exactly is electron promotion?

I was also confused on this! I just googled it and it says that electron promotion is when an electron absorbs a photon to jump from a low energy level orbital to a higher one.

When you are asked to show hybridization via electron promotion on a box diagram the problem wants you to show, as an example, the movement of an electron from the 2s to 2p orbital allowing for hybridization of the s and p orbitals to sp.
