Overview
Neon is a colorless, inert noble gas notable for its bright emission in discharge lamps.
Properties
It is chemically inert, has low boiling point and produces characteristic red orange glow in neon signs.
Occurrence and Uses
Present in trace atmospheric amounts, neon is used in lighting, high voltage indicators and some cryogenic applications.
Isotopes and Safety
Stable isotopes include Ne 20, Ne 21 and Ne 22; neon is nonreactive and poses minimal chemical hazard aside from asphyxiation risk in confined spaces.
