Coined/History
It is amazing that in 42 days in 1908 English chemist Morris W.
Travers (1872–1961) discovered three chemical elements neon, xenon, and
krypton. From 1895 untill 1900 Travers
worked with English chemist (sir) William Ramsey (1852-1916) to find the
missing gases that the periodic Table indicated should exist. They chilled a sample of atmosphere until it
became liquid, then warmed the liquid and captured the gases as they boiled
off. The two managed to isolate krypton in May 1898, and them a few
days later, while examining a large
volume of argon, they separated a small quantity of elements which were mamed
by Ramsey as neon and xenon. Travers later wrote “ the blaze of crimson light from the tube
told its own story and was a sight to dwell upon and never forget… For the
moment the actual spectrum of the gas did not matter in the least, for nothing
in the world gave a glow such as we had seen.”
Definition
Neon is chemical element with atomic number 10 and
atomic mass 20.1797 . It is colorless, inert noble gas that used for neon
sighns. Neon with helium are used for gas lasers. It is commercially extracted
from air in whisc it is found in trace amounts (1 part per 65,ooo of air).
