Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.

Polar covalent bonds give/take electrons, while nonpolar covalent bonds share electrons.

Answer 1

"Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally."

Reason: In polar covalent bonds the atoms have different electronegativities so the shared electrons are pulled more toward one atom, creating partial charges (a dipole). In nonpolar covalent bonds the atoms have similar electronegativities so electrons are shared evenly.
