Why does Argon have a zero valency?

brainliest for the right answer

If you asking about the neon and argon thing then I'll answer it tho!

Neon and Argon's are fully filled electron's in their 1 st shell or most likely it's outermost shell which have 8 electron's in total and it cannot take or loose any of them and it can't even share it tho to anyone and that's why  argon have a zero valency

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
