What Is the Density of Neon?

Neon is 0.9 grams per liter making it the 113th most dense element out of 118. It is about two-thirds the density of air. Neon is a colorless, odorless, inert, monatomic gas that is part of the noble gases.

Neon was discovered in London, England in 1898 by Scottish chemist Sir William Ramsay and English chemist Morris W. Travers. The name neon originates from the Greek word "neon" meaning "new." Neon has many different uses, the largest is to make brightly lit signs. It is also used to make high voltage indicators, and it is combined with helium to make helium-neon lasers.
