True
False
8. Explain the difference between a polar covalent bond and a nonpolar covalent bond.
9. Describe how the number of lone pairs on the central atom affects the molecular geometry.
Use the words below to complete the sentences.
10. Atoms tend to gain, lose, or share electrons to achieve a stable electron configuration, typically with eight valence electrons, which is known as the .
11. A bond formed by the transfer of electrons from one atom to another is called an bond.
