Ground-State Electron:

A ground-state electron refers to an electron that occupies the lowest available energy level in an atom or molecule.

Excited State: An excited state occurs when an electron absorbs energy and moves to a higher energy level than its ground state.

Photon:

A photon is a particle of light that carries a specific amount of energy. It can be emitted or absorbed by electrons during transitions between energy levels.
