ARBOR SCIENTIFIC NEON WAND TUBE NEW

Description

Hold the wand by the insulating handle. Bring it near a running Van de Graaff Generator, and observe the tube lighting up. (Darken the room for a more dramatic demonstration.)
Neon is commonly used in lighting applications because it ionizes easily. When the tube of neon gas
is brought into the strong electrostatic field near the generator, the field energizes the electrons on
the gas atoms. That is, the electrons gain energy and come out of their atomic orbitals, leaving
again, creating a neutral particle and releasing energy in the form of light.
positively charged neon ions. When a free electron comes near a neon ion, it can “fall” into orbit
Note that electricity is not flowing through the tube. The tube is simply placed in a strong
The color of the light is characteristic of neon and its energy levels. Different colors can be created
by using different gases or by adding impurities to the neon.
