CHEM 1405 CHAPTER 4
... When energy is given to an atom in the form of heat energy or electrical energy, the electrons in the atom get excited to higher energy levels by absorbing energy. This is the excited state of an atom, which is unstable. The electrons then start falling from higher levels to lower levels, releasing ...
