| 1) Element name: Neon
2) Element symbol: Ne
3) Number of electrons, protons, and neutrons: 10 electron, 10 proton, 10 neutrons
4) Atomic number: 10
5) Atomic mass: 20.179
6) Characteristics: Neon is a colorless, odorless, monatomic gas.
7) History: It was first separated from other inert gases in 1898 by the British chemist Sir William Ramsay and Moris Travers (1872-1961). The first demonstration of the existence of a stable isotope in an element was performed with neon in 1912. Three things made from the element: - neon produces a crimson glow in a vacuum electric-discharge tube and is used extensively in the familiar neon light of advertising displays - liquid neon is used as a cryogenic refrigerant - used in high-voltage testers
8) Isotopes: Neon occurs naturally in three stable isotopes: Neon-20, which is the most abundant isotope, neon-21, and neon-22.
9) No stable chemical compounds of neon have been observed. Molecules of the element consist of single atoms.
