Which among the following is correct statement?
Ionic radii does not depend upon effective nuclear charge
Ionic radii increase with increase in effective nuclear charge
Ionic radii decreases with increase in effective nuclear charge
None of the above
The electrons in the valence shell experience an attractive force from the nucleus and a
repulsive force from the electrons in the inner shells. Due to this repulsive force caused
by inner electrons, the net attractive force exerted by the nucleus on the valence shell
electrons is somewhat reduced. The actual charge felt by the valence shell electrons is
called effective nuclear charge.
Therefore, higher the effective nuclear charge felt by valence shell electrons, lesser the
ionic radii.
