It's quite simple
We know
Atomic no =no of proton=no of eletron
So by Atomic no we are able to identify no of elctron.
Simply arrange the electron in a shell .
If it gains electron from others then it is electronegative (Non Metal).
Similarly if it loses electron then it is electropositive (Metal).
All I want to say is Electropositive elements are metal whereas electronegative elements are non metal.
