Question

what is meant by Atomic radius?? Explain it very easy to understand..​

Answer 1

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. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius.

Answer 2

Answer:

Atomic radius or Atomic Radii is the total distance from the nucleus of an atom to the outermost orbital of its electron. ... The radii of atoms are therefore determined by the bonds they form. An atom will have different radii depending on the bond it forms; so there is no fixed radius of an atom.
