Compare the radii of H atom, H^(+) ion and H^(-) ion.

1.	Compare the radii of H atom, H^(+) ion and H^(-) ion.
Answer» Solution :`H^+` is the NUCLEUS of H atom. Its RADIUS is very small. H-ion has number of ELECTRONS more than number of PROTONS. Its size is more than that of H atom.The radius is in the order : `H^(+) < H < H^(-)`.
