Electronegativity (EN)

Definition

Electronegativity is a measure of an atom's ability to attract and hold onto electrons when it is part of a compound. The higher the electronegativity value, the more strongly an atom can pull electrons towards itself.

Polar Covalent Bond: A type of chemical bond where two atoms share a pair of electrons unequally due to a significant difference in electronegativity.

Nonpolar Covalent Bond: A chemical bond where two atoms share a pair of electrons equally because they have similar or identical electronegativity values.

Dipole Moment:

A measure of the separation of positive and negative electrical charges within a molecule, often resulting from differences in electronegativity
