What is a polar covalent bond?

Answer 1

== == When two elements of different electronegativities (any two different elements) bind chemically, the electrons associated with the bond will naturally spend more time "flying around" the more electronegative atom's nucleus. This results in the more electronegative atom having a partial negative charge and the less electronegative atom have an equal but opposite positive charge.

Answer 2

A polar covalent bond occurs when two atoms share electrons unevenly due to differences in electronegativity. This results in a partial positive charge on one atom and a partial negative charge on the other, creating a dipole moment within the molecule.
