Ne-21 Information

Neon is a colourless gaseous element of group 18 on the periodic table (noble gases). Neon occurs in the atmosphere, and comprises 0.0018% of the volume of the atmosphere. It has a distinct reddish glow when used in discharge tubes and neon based lamps. This element forms almost no chemical compounds. Neon was discovered in 1898 by Sir William Ramsey and M.W. Travers. Neon has 19 isotopes, 3 of them are stable.

Neon is used primarily for lighting.
