All the noble gases, except for helium, have 8 valence electrons. Helium has actually 2 valence electrons. The valence electrons get involved in chemical bonding processes and are existing in the outermost shell. Noble gases space the least reactive of every elements and have a completely filled outer shell that electrons.

Valence electrons room the electron in the outermost covering of one atom of a offered element. This electrons get involved in the shortcut formation, as lengthy as the external shell is not fully filled.
The valence electrons deserve to be donated or embraced in an ionic bond or mutual in a covalent bond.
Noble gases are the elements of team 18 that the routine table of elements. These aspects include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and also radon (Rn). The noble gases are likewise known together inert elements, since they have really low chemistry reactivity— the is, the atoms of these facets (or noble gases) rarely participate in a chemical reaction.
The noble gases monitor the dominion of octet. In other words, their outermost shells contain 8 electrons, other than for helium, who outermost shell has 2 electrons. The valence electrons of the noble gases are provided as a typical of nonreactivity, and also the reactivity of other facets is defined in regards to their desire to accomplish the same level the valence electrons as the noble gases. In various other words, as soon as bonding take away place, electrons room shared/exchanged in together a means that the connecting atoms achieve a completely filled external shell the electrons.
Also, keep in mind that even though helium has actually only 2 electron in the outermost shell, the still has actually the fully filled shell and also its construction is 1s2.

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