the visible spectrum of atomic neon

Ne - Neon

This inert gas is well known for its orange light seen in 'neon signs'. Neon (as well as krypton, xenon and radon.) was extracted by William Ramsey and M. W. Travers from liquid air in 1898 in London. The emission spectrum of neon may be demonstrated to our general chemistry students.
