Question

What are SI
units of atomic radius

Answer 1

Answer:

The units for atomic radii are picometers, equal to 10−12 meters. As an example, the internuclear distance between the two hydrogen atoms in an H2 molecule is measured to be 74 pm.

Answer 2

Answer:

Atomic radii are usually expressed in terms of either the SI unit of nanometers or picometers. Picometer is the common unit of atomic radius.

Explanation:

The SI unit of length is the meter however because the atomic radius is so small, it is commonly given in nm (nanometer) or pm (picometer)

Picometers, or $10^{-12}$ meters, are the units for atomic radii. The internuclear distance between two hydrogen atoms in an $H_{2}$ molecule, for example, is measured at 74 pm.

1 picometer = $10^{-12} m$

One-half the distance between the nuclei of identical atoms that are bonded together is known as the atomic radius.
