Which halogen has the least attraction for electrons?

Answer 1

Astatine, #At#

All halogens are electronegative because they have naturally 7 eletrons with them, only needing one more to become stable due to the octet rule.

However, since smaller atoms and molecules have a bigger charge density, they're usually more electronegative than bigger atoms, so the least electronegative halogen will be the one the further down on the periodic table, which as of time of writing is Astatine (#color(white)(.) _85^(210) At#).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
