What is Atomic Radius?
An atomic radius is half the distance between adjacent atoms of the same element in a molecule.
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.
