Final answer:
A trigonal bipyramidal shape has three atoms in equatorial positions separated by 120° from each other and two axial positions forming 90° angles to the equatorial plane.
Step-by-step explanation:
The student has asked to draw a trigonal bipyramidal molecular shape, also known as AX5, and provide the angle measurements for this shape. In a trigonal bipyramidal geometry, the central atom is surrounded by five attached atoms. Three of these atoms occupy positions in the same plane, forming the trigonal planar base with each bond angle between them being 120°. The remaining two atoms are positioned above and below the trigonal plane in what are called the axial positions, forming 90° angles relative to the plane of the three equatorial atoms. This molecular shape is common in certain compounds such as phosphorus pentachloride (PCl5).
