Neon Bohr ModelNeon is a Block P, Group 18, Period 10 element. The number of electrons in each of Neon's shells is 2, 8 and its electronic configuration is 1s2 2s2 2p6. In its elemental form neon's CAS number is 7440-01-9. The neon atom has a covalent radius of and it's Van der Waals radius is Neon is found in small amounts in the Earth's atmosphere and is commercially produced by cryogenic fractional distillation of liquefied air. Neon was discovered and first isolated by Sir William Ramsay and Morris W. Travers in 1898. The origin of the name comes from the Greek word neon meaning new
