WebAn electron can be excited when its absorbs energy from electromagnetic radiation. Different changes in energy level need different frequencies of electromagnetic radiation. WebElectrons and photons can impact atoms. The impact of electrons and photons injects energy into the electrons orbiting the atom. The energy of the electrons changes, exciting them and making them jump to another orbit or even ejecting them. Electrons that are not excited are said to be in their ground state.
