Question

What is mean by atomic radius? Write the unit of measuring atomic radius?​

Answer 1

Answer:

The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together. ... 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:

• atom is considered as a spherical body
• a line that can be formed from the centre of the atom to the outermost part of the electron is known as atomic radius
• atomic radius can be measured in many units
• one such unit is nanometre represented as NM
• 1 metre is equal to 10 raise to 9 nanometre
• another unit which can be used to measure the atomic radius is angstrom
• 1 angstrom is equal to 10 raised to negative 10 metre
