What is also true about a polar molecule?

• The molecule is ionic.

• Each side of the molecule has a small charge.

• The molecule has no charge at all.

• The molecule has at least 15 atoms.

A polar molecule makes _______ bonds with other polar molecules.

• ionic

• hydrogen

• helium

• nonpolar

Why is the molecule polar?

• There is a nonbonding pair on the central atom.

• There are different types of elements bonded to the central atom.

• There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.

In order to determine if a molecule is polar, you must consider the

• polarity of bonds and symmetry of the molecule.

• number of electrons and number of bonds.

• polarity of bonds only.

• total charge of each ion and number of multiple bonds.

Why is the molecule polar?

• There are nonbonding pairs on the central atom.

• There are different types of elements bonded to the central atom.

• There are no nonbonding pairs on the central atom and all of the atoms bonded to the central atom are the same.
