Electron Excitation, De-Excitation And Ionisation

Question 1

Electron excitation is…

Answer 1

…electrons getting excited and moving up electron shells because the atom has absorbed electromagnetic radiation

Question 2

Electron de-excitation is…

Answer 2

…electrons moving back down the electron shells as it releases the electromagnetic radiation

Question 3

Electron ionisation is…

Answer 3

…the process of an atom rejecting or gaining an electron. These atoms are known as ions, and no longer have a neutral charge. If an atom gains an electron, it becomes negative but if it loses an electron it becomes positive
