Question

Atomic radius is expressed in the unit picometer (pm) which is smaller than nanometer 
​

Answer 1

Explanation:

The picometre (international spelling as used by the International Bureau of Weights and Measures; SIsymbol: pm) or picometer (American spelling) is a unit of length in the metric system, equal to 1×10−12 m, or one trillionth (1/1000000000000) of a metre, which is the SI base unit of length.

The picometre is one thousandth (1/1000 × nm) of a nanometre, one millionth of a micrometre (also known as a micron), and one trillionth of a meter.[2]The symbol μμ was once used for it.[3] It is also one hundredth of an Ångström, an internationally recognised (but non-SI) unit of length.
