What is happening to the electrons in a polar covalent bond?

• They are being shared equally.

• They are being shared unequally.

• They are not being shared at all.

• They are gained or lost and held together by electric charges.

What is happening to the electrons in a nonpolar covalent bond?

• They are being shared equally.

• They are being shared unequally.

• They are not being shared at all.

• They are gained or lost and held together by electric charges.

In an ionic bond, the electrons...

• are being shared unequally

• are not being shared, but gained or lost

• are being shared equally
