Answer:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

Explanation:

metallic radius is defined as one-half of the distance between the nuclei of two atoms in crystal or between two adjacent metal ions in the metallic lattice

Answer 2

metallic radius :

in chemistry , metallic radius is distance between the nuclei of two atoms in crystal or between two adjacent metal ions in the metallic lattice.

atomic radius :

atomic radius means one-half the distance between the nuclei of identical atoms that are bonded together.
