### Electron Withdrawing Power

What is an atom's electron withdrawing power? Is it the same as electronegativity?

Electron withdrawing power is how good an atom is at pulling an electron away from another atom. It is like electronegativity in the sense that an atom with higher electronegativity and usually a smaller radius will have more electron-withdrawing power. Example: Fluorine has greater electron withdrawing power than chlorine, because it is smaller and more electronegative.

Can someone explain how e- withdrawing power relates to oxyacids? I don't understand what the notes meant by "e- withdrawing tons delocalize and stabilize the negative charge"

In respect to oxacids, acids with a greater amount of oxygen will be stronger because the electrons of the resulting anion are more delocalized. This is due to the high electronegativity of oxygen.
