Iso-electronic species
Which ion has the lowest radius from the following ions(a) Na+ (b) Mg2+ (c) Al3+ (d) Si4+ Answer: (d) All are the iso-electronic species but Si4+ has high positive charge so have lowest radius.

The Schrodinger wave equation generalizes the fitting-in-of-waves procedure.The waves that "fit" into the region to which the particle is contained can be recognized "by inspection" only for a few simple systems. For other problem a mathematical procedure
