As of 2008, endohedral complexes with helium, neon, argon, krypton, and xenon have been created. [64] These compounds have found use in the study of the structure and reactivity of fullerenes by means of the nuclear magnetic resonance of the noble gas atom.

Neon's polarisability of 0.395 Å 3 is the second lowest of any element (only helium's is more extreme). Low polarisability means there will be little tendency to link to other atoms. [1] Neon has a Lewis basicity or proton affinity of 2.06 eV. [2] Neon is theoretically less reactive than helium, making it the least reactive of all the elements ...
Neon also forms an unstable hydrate. [23] There is some empirical and theoretical evidence for a few metastable helium compounds which may exist at very low temperatures or extreme pressures. The stable cation [HeH] + was reported in 1925, [ 24 ] but was not considered a true compound since it is not neutral and cannot be isolated.
[39] [58] This creates an analogous series in which the outer shell structures of sodium through argon are analogous to those of lithium through neon, and is the basis for the periodicity of chemical properties that the periodic table illustrates: [39] at regular but changing intervals of atomic numbers, the properties of the chemical elements ...
Neon pothos is known for its air-purifying qualities. Like other pothos varieties, it can help remove toxins such as formaldehyde, benzene, and xylene from the air.
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z). Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
