1.	In a given transition series, there is no significant change in the atomic radii of elements with an increase in atomic number. Explain why.
Answer» In a transition series, with increasing atomic number, the nuclear charge increases. The electrons are added into penultimate d-subshell. The added delectrons shield the outermost electrons. As d-electrons increase shielding effect also increases. This counterbalances the increased nuclear charge. As a result, there is no significant change in the atomic radii of elements with an increase in atomic number.
