Understanding Covalent and Ionic Bonds

What is the primary difference between covalent and ionic bonds?

• Covalent bonds involve sharing electrons, while ionic bonds involve transferring electrons.

• Covalent bonds occur between metals, while ionic bonds occur between nonmetals.

• Covalent bonds involve the transfer of electrons, while ionic bonds involve sharing.

• Covalent bonds are weaker than ionic bonds.

Which groups on the periodic table are primarily nonmetals?

• Groups 1 and 2

• Groups 3 and 4

• Groups 5, 6, and 7

• Groups 8 and 9
