It is in group 18 (noble gases) of the periodic table. The atomic number of neon is 10. P71 Neon, a noble gas, was discovered in 1898 by William Ramsay and Morris Travers. They are also used as Nixie tubes which are electronic devices to display numerals or other info using glow discharge. Classified as a noble gas, Neon is a gas at room temperature. Brief history of how this atom was discovered-in 1898 by the British chemist’s Sir William Ramsay and when Ramsay chilled a sample of air until it became a liquid, then warmed the liquid and captured the gases as they boiled off.6.
