Define electronegativity. where on the periodic table is the highest? explain why this is the case.

Explanation:

Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity values generally increase from left to right across the periodic table. The highest electronegativity value is for fluorine.

a polar bond is formed when electrons are shared unevenly between atoms
