All the noble gases, except for helium, have 8 valence electrons. Helium has 2 valence electrons. The valence electrons participate in chemical bonding processes and also are present in the outermost shell. Noble gases room the the very least reactive of every elements and have a fully filled outer shell that electrons.

Valence electrons room the electron in the outermost shell of one atom of a offered element. This electrons take part in the bond formation, as lengthy as the outer shell is not completely filled.

The valence electrons deserve to be donated or embraced in an ionic bond or shared in a covalent bond.

Noble gases space the aspects of team 18 that the periodic table that elements. These aspects include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and also radon (Rn). The noble gases are also known together inert elements, due to the fact that they have really low chemical reactivity— that is, the atoms of these facets (or noble gases) rarely participate in a chemistry reaction.

The noble gases follow the dominion of octet. In various other words, their outermost shells contain 8 electrons, other than for helium, whose outermost shell has 2 electrons. The valence electron of the noble gases are supplied as a standard of nonreactivity, and also the reactivity of other aspects is defined in terms of their desire to accomplish the very same level the valence electrons together the noble gases. In various other words, when bonding bring away place, electrons space shared/exchanged in such a means that the interacting atoms achieve a totally filled external shell of electrons.

Also, keep in mind that also though helium has actually only 2 electrons in the outermost shell, that still has the totally filled shell and also its configuration is 1s2.

In summary, the noble gases have 8 valence electron each, other than for helium, which has 2 valence electrons.
