We are told that the noble gases, with their atomic numbers, are: helium 2, neon 10, argon 18, krypton 36, xenon 54, radon 86, and ununoctium 118.Thus, the sizes (number of elements) of the rings of electrons around the nucleus are the differences between the atomic numbers: 2, 8,...
atomic number 10 - a colorless odorless gaseous element that give a red glow in a vacuum tube; one of the six inert gasses; occurs in the air in small amounts Ne, neon chemical element, element - any of the more than 100 known substances (of which 92 occur naturally) that cannot be...
The EAN rule was coined by English chemist Nevil V. Sidgwick, who observed that in a number of metal complexes, the metal atom tends to surround itself with enough ligands that the resulting effective atomic number is numerically equal to the atomic number of the noble-gas element found in t...

Helium is one of thenoble gases or inert gases, which means it has a complete electron valence shell so it's not reactive. Unlike gas ofatomic number 1(hydrogen), helium gas exists asmonatomicparticles. The two gases have comparable mass (H2and He). Single helium atoms are so small they...
