Final answer:
The shape with 3 bonds, 0 lone pairs, and 120° bond angles is trigonal planar, as the electron groups are spaced evenly to minimize repulsion.
Step-by-step explanation:
The shape that has 3 bonds, 0 lone pairs, and bond angles of 120° is trigonal planar. This is because a molecule with three electron groups around the central atom will orient the groups as far apart as possible which results in a trigonal planar shape, maintaining 120° angles between each bond. An example of such a molecule is BF3, where the boron is the central atom with three fluorine atoms evenly spaced around it in a single plane.
