The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms. Electron configurations of elements beyond hassium (element 108) have never been measured; predictions are used below. As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule.

Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]

Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2
Azide (-⅓) (the reductant, electron donor) is oxidized in N 2 (0), nitrous oxide (N 2 O) (+1), or nitric oxide (NO) (+2) while nitrite (+3) (the oxidant, electron acceptor) is simultaneously reduced to the same corresponding species in each elementary redox reaction considered here above.
However, by removing one electron from dihelium, the stable gas-phase species He + 2 ion is formed with bond order 1/2. Another molecule that is precluded based on this principle is diberyllium. Beryllium has an electron configuration 1s 2 2s 2, so there are again two electrons in the valence level. However, the 2s can mix with the 2p orbitals ...
