which si unit of length is most commonly used to indicate the radius of an atom?\na 1 picometer (pm)\nb 1 nanometer (nm)\nc 1 micrometer (μm)\nd 1 millimeter (mm)

Answer

Brief Explanations:

Atoms are extremely small. Picometers are the most appropriate SI - unit for measuring atomic radii as atoms have radii in the range of a few tenths to a few hundred picometers. Nanometers, micrometers, and millimeters are much too large for this purpose.

Answer:

A. 1 picometer (pm)
