Question

____ covalent bonds occur when atoms share a pair of electrons in a covalent bond equally. if this is true for all bonds in a molecule, that molecule will be neutral.

a. polar
b. nonpolar
c. ionic
d. metalic

Explanation:

To solve this, we analyze each option:

• Option a (Polar): In polar covalent bonds, electrons are shared unequally, so this is incorrect.
• Option b (Nonpolar): Nonpolar covalent bonds involve equal sharing of electron pairs. If all bonds in a molecule are nonpolar covalent, the molecule is neutral, which matches the description.
• Option c (Ionic): Ionic bonds involve transfer of electrons, not equal sharing, so incorrect.
• Option d (Metallic): Metallic bonds involve a sea of electrons, not equal sharing of electron pairs in a covalent - like way, so incorrect.

Answer:

b. Nonpolar
