Question

why oxidation number of noble gases is usually zero?why













​

Answer 1

Answer:

Because they are inert.

they generally don't form compounds with most of the elements (I know exceptions occur).

Their electronegativity can be rounded to zero with no doubt.

so they will not get any partial charge on them even in a compound.

Explanation:

exceptions include gases like xenon and krypton which forms compounds with some highly electronegative elements.
