The chemistry expression "noble gas configuration" refers to the electron configuration of an element. The noble gas configuration for neon is denoted as 1s2 2s2 2p6. More »

A condensed electron configuration is also known as noble gas notation because it uses the last noble gas of the row above the row containing the element being notated to shorten the electron notation for the element. Co... More »

Neon (Ne) is the most common noble gas used in neon signs. The term "neon signs" comes from its frequent use as a lighting agent. More »

Hydrogen does not have a noble gas configuration because it its the first element on the periodic table. Only elements that fall after the noble gases on the periodic table can have noble gas configurations. More »

Neon is its own chemical element, not a compound of elements. Neon is an inert gas and part of the noble gases group in the periodic table. More »

Noble gases are unreactive because their outer electron shells are full and therefore in their most stable state. Normally, elements react with one another because they have incomplete electron shells. They lose, gain or... More »

The S2- ion, the simplest sulfur anion and also known as sulfide, has an electron configuration of 1s2 2s2 2p6 3s2 3p6. A neutral atom of sulfur has 16 electrons, but the atom then gains an additional two electrons when ... More »
