Front

What shape is a molecule with two bonding pairs and one lone pair?

Back

Bent

Front

What shape is a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral

Front

What is the result when two atoms are too close together?

Back

They will repel each other.

Front

What happens when two atoms are at an optimal distance?

Back

They have forces perfectly balanced between repulsion and attraction.

Trigonal pyramidal

Front

What does a linear molecular shape indicate about the bond angles?

Back

The bond angles are 180 degrees.

Front

What is the bond angle in a trigonal planar molecular shape?

Back

120 degrees.
