Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air. Neon was discovered in 1898 alongside krypton and xenon, identified as one of the three remaining rare inert elements in dry air after the removal of nitrogen, oxygen, argon, and carbon dioxide.
Monoatomic (composed of one atom). Examples include He , Ne , Ar , and Kr . All noble gases are monoatomic. Diatomic (composed of two atoms). Examples include H 2 , N 2 , O 2 , F 2 , and Cl 2 . Halogens are usually diatomic. Triatomic (composed of three atoms). Examples include O 3 .
One mole of atoms contains an Avogadro number of atoms, so that the energy of one mole of atoms of a monatomic gas is =, where R is the gas constant. In an adiabatic process , monatomic gases have an idealised γ -factor ( C p / C v ) of 5/3, as opposed to 7/5 for ideal diatomic gases where rotation (but not vibration at room temperature) also ...
The neon atoms are attracted to the beryllium atoms as they have a positive charge in this molecule. [23] Beryllium sulfite molecules BeO 2 S, can also coordinate neon onto the beryllium atom. The dissociation energy for neon is 0.9 kcal/mol. When neon is added to the cyclic molecule, the ∠O-Be-O decreases and the O-Be bond lengths increase. [24]

This represents a localization of charge that is facilitated by the high electronegativity of fluorine. [68] The chemistry of the heavier noble gases, krypton and xenon, are well established. The chemistry of the lighter ones, argon and helium, is still at an early stage, while a neon compound is yet to be identified.
