Answer:
Atomic radius of an element is the measure of the distance between the nucleus and the outermost shell of the element.
Step-by-step explanation:
The atomic radius is the radius of the atom. It can be measured as the distance between the nucleus and the outermost shell of the element. The atomic radius increases as the binding energy of the outermost electrons with the nucleus decreases.
The atomic radius of a compound were classified into five types based on the bonding occurring in the compound.
They are
(i) Van der Waals radius,
(ii) ionic radius,
(iii) covalent radius,
(iv) metallic radius and
(v) Bohr radius.
The first four types of atomic radii are the measure of atomic radii of atoms combined to form a molecule or compound using the bonding type present in their names itself. The Bohr radius is the distance of the lowest energy electron orbit from the nucleus.
