let X be any hypothetical isolated neutral atom and X- be the anion formed when X gain 1 electron

this extra electron is in the valence energy orbit(band) and X- being charged produces electric field

check me if i m wrng above


now X(neutral) also consists of electrons in the valence band but it does not produce electric field in the space ?

can u pl explain the mechanisms involved .....
