Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed.

Atomic Number of Neon. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. The chemical symbol for Neon is Ne.. Atomic Mass of Neon. Atomic mass of Neon is 20.1797 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.

Relative atomic mass The mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average. Isotopes Atoms of the same element with different numbers of neutrons. CAS number

Neon (10 Ne) possesses three stable isotopes, 20 Ne, 21 Ne, and 22 Ne. In addition, 17 radioactive isotopes have been discovered ranging from 15 Ne to 34 Ne, all short-lived. The longest-lived is 24 Ne with a half-life of 3.38 minutes. All others are under a minute, most under a second.

Calculating Atomic Mass. You can calculate the atomic mass (or average mass) of an element provided you know the relative abundances (the fraction of an element that is a given isotope), the element's naturally occurring isotopes, and the masses of those different isotopes.We can calculate this by the following equation:
