Question

i dont understand what is atomic radii

Answer 1

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. ... Electrons do not have definite orbits nor sharply defined ranges.

Answer 2

Explanation:

The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together. Figure 1. The atomic radius (r) of an atom can be defined as one half the distance (d) between two nuclei in a diatomic molecule. Atomic radii have been measured for elements.
