Ne element symbol8/31/2023 By going through the periodic table, we see that the electron-dot symbol of atoms will never have more than eight dots around the atomic symbol. Element - Neon Symbol - NE Atomic number - 10 Discovery - Neon was discovered in 1898 by Sir William Ramsay and Morris Travers. The word neon comes from the Greek word for new. Five other unstable isotopes of neon are known. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). With the exception of helium, all of the noble gases have names ending in -on. Travers 1898 (England) Electron Configuration: He2s 2 2p 6 Word Origin: Greek neos: new Isotopes: Natural neon is a mix of three isotopes. It is a tabular arrangement of the elements by their chemical properties that usually uses abbreviated chemical symbols in place of full element names, but the linear list format presented here is also useful. With the next element, sodium, the process starts over with a single electron because sodium has a single electron in its highest-numbered shell, the n = 3 shell. Symbol: Ne Atomic Weight: 20.1797 Discovery: Sir William Ramsey, M.W.
