INTRODUCTION
The Franck-Hertz experiment for neon involves observing how energy is transferred from electrons as a result of inelastic collision while passing through neon gas. The transfer of energy occurs in discrete steps corresponding to the excitement by such collision of distinct energy level transitions in the neon atoms. The excited atoms then emit visible light (3B Scientific ® Physics). This experiment provides a hands-on demonstration of atomic excitation by electron impact and measurement of atomic excitation energy of mercury and (in this case) neon. It is one of the key demonstrations of the quantum behavior of atoms and provides a direct non-optical demonstration of the existence of discrete stationary energy levels in atoms (Wiley & Sons, 1985).
