According to the Octet Rule, the most valence electrons any atom can have is 8. Atoms naturally want to meet this rule either by losing or gaining enough electrons to have a total of 8 valence electrons. The nobel gases have exactly 8 valence electrons. The neither need to lose or gain any and therefore do not play well with others. The losing or gaining of valence electrons determines the stability and reactivity of the element.
It is the noble gas family or the group XVIII.
Group-18 belongs to noble gases. The elements of this group are stable.
Helium is under group 18 and period 1. This makes helium a noble gas with the most electrons it can possibly have under stable conditions.
The Noble Gas group, which is Group 18.

Group-18 belongs to noble gases. The elements of this group are stable.
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
The noble gas group because their outermost shell of electrons is completely full unlike the other groups.
Helium (He) is a noble (inert) gas placed in the group 18 of the Periodic Table.Helium falls in inert gas. It is stable and non-reactive.
Helium is under group 18 and period 1. This makes helium a noble gas with the most electrons it can possibly have under stable conditions.
all elements in group 8 are very stable as they have 8 electrons in their outermost electron shell, satisfying the octet rule. They are very stable and are called noble gas. they exist in a monoatomic gas.
The Noble Gas group, which is Group 18.
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.

Neon is a noble gas because it has a complete octat and it is stable in its ground state.
It is in Group O or Group 8. Also known as noble gas, they do not react with other elements as they do not have to react to get a stable configuration.
