All the noble gases, except for helium, have 8 valence electrons. Helium has 2 valence electrons. The valence electrons take part in chemical bonding processes and also are existing in the outermost shell. Noble gases space the the very least reactive of all elements and have a totally filled outer shell the electrons.

Valence electrons space the electron in the outermost covering of an atom the a provided element. These electrons get involved in the shortcut formation, as lengthy as the outer shell is not fully filled.
The valence electrons have the right to be donated or embraced in an ionic bond or mutual in a covalent bond.
Noble gases room the facets of group 18 that the regular table the elements. These facets include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and also radon (Rn). The noble gases are likewise known as inert elements, since they have an extremely low chemical reactivity— that is, the atom of these facets (or noble gases) rarely take part in a chemistry reaction.
The noble gases follow the dominion of octet. In various other words, your outermost shells contain 8 electrons, other than for helium, whose outermost shell has 2 electrons. The valence electron of the noble gases are provided as a typical of nonreactivity, and the reactivity of other elements is described in terms of their desire to achieve the very same level the valence electrons together the noble gases. In various other words, once bonding bring away place, electrons are shared/exchanged in such a means that the communicating atoms attain a fully filled outer shell the electrons.
Also, keep in mind that even though helium has only 2 electron in the outermost shell, that still has the fully filled shell and also its configuration is 1s2.

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