Question

In transition series with an increase in atomic number the atomic radius does not change very much why

Answer 1

Because when transition elements reacts with metals then they are strong bond but also they dont get out......

Answer 2

Hey !!

With the increase in atomic number along a transition series the nuclear charge increases which tends to decrease the size of the atom. But the addition of electrons in the d- subshell increases the screening effect which counter balances the increased nuclear charge.

     Hence, along a transition series the atomic radius does not change very much.

Good luck !!
