Question

which of the following best describes a polar covalent bond? a bond in which electrons are shared equally between two atoms. a bond in which one atom gains an electron and another loses an electron. a bond where electrons are shared unevenly between two atoms, resulting in a partial charge. a bond that occurs between two nonmetals with identical electronegativities.

Explanation:

A polar covalent bond is characterized by unequal sharing of electrons between two atoms due to a difference in electronegativities, leading to partial charges on the atoms. In a non - polar covalent bond, electrons are shared equally. When one atom gains and another loses an electron, it's an ionic bond. Bonds between non - metals with identical electronegativities are non - polar covalent.

Answer:

A bond where electrons are shared unevenly between two atoms, resulting in a partial charge.
