It is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold.You know because it is in group 8A of the periodic table, therefore it has 8 valence electrons. The group number tells you how many electrons are in the valence shell.:).t is a noble gas, meaning it has the maximum number of valence electrons its outer shell can hold.

For most elements, the valence shell takes eight electrons to fill. According to the octet rule, an atom is âcompleteâ when its valence shell has eight electrons; incomplete atoms share electrons and in so doing end up with full valence shells.or the carbon dioxide molecule, for example, one carbon atom bonds with two oxygen atoms. Carbon, with four electrons in its valence shell, needs four to reach the octet state. Oxygen, with six outer electrons, needs two.
