Heyy dear♥️
Noble gases has zero valency because its combining capacity is zero. They have complete octate. So they are stable and do not need any removal or addition of electron for the competion of octet.
The outermost shell of a noble gas 8 electrons.
So it's valency = (8 - 8) = 0
Hope you got it :)
