Can someone tell me how I find the atomic radius of atoms and what they are. Thank yo

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms and then halving that distance. Measuring the atomic radii of chemical elements is a complicated task as the size of an atom is of the order of 1.2×10-10 m. The electron cloud forming the shell of an atom does not have any fixed shape which makes it difficult to determine the atomic size of an atom. So we can say that practically we cannot determine the size of an individual atom.

Atomic Radius:

Atomic radius is the distance from the center of the nucleus to the outermost shell containing electrons.
