Write in the number of lone pairs or atoms to complete each description below. a molecule that has a trigonal-planar shape has lone pairs a molecule that has a bent shape and a trigonal-planar electron domain shape has lone pairs. a molecule that has a trigonal-pyramidal shape has ato ms and lone pair around the central atom.

1. A molecule with a trigonal-planar shape has no lone pairs on the central atom.

An example is BF₃ (see Figure 1).

2. A molecule with a bent shape and a trigonal-planar electron domain shape has one lone pair on the central atom.

An example is SO₂ (see Figure 2).

3. A molecule that has a trigonal-pyramidal shape has three atoms and one lone pair around the central atom.

An example is NH₃ (see Figure 3).
