Except _____ gas all other noble gases have octet in their valence shell.

(A) Noble gases have very high ionization enthalpies in periodic table (R) All noble gases have stable octet configuration in their valence shell

Except this all the noble gases have eight electrons in their outermost shell.

All noble gas molecules are

The valency of noble gases is-

Passage-IV : Sulphur and rest of the elements of group 16 are less electronegative than oxygen. Therefore, their atoms cannot take up electrons easily. They can acquire ns^(2)np^(6) configuration by sharing two electrons with the atoms of other elements and thus, exhibit +2 oxidation state in their compounds. In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the shell. As a result, they can show +4 and +6 oxidation states shell. The nature of the compounds of sulphur having +4 oxidation state is :

In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the shell. As a result, they can show +4 and +6 oxidation states shell. Like sulphur, oxygen does not show +4 and +6 oxidation states. The reason is :

Why Noble gases have zero electron gain enthalpy?

Why do inert gases have zero valency value ?

Why do noble gases have comparatively large atomic sizes ?
