Question

Given below are two statement : one is labelled as Assertion A and the other is labelled as Reason R :

Assertion A : Size of ${Bk}^{3 +}$ ion is less than ${Np}^{3 +}$ ion.

Reason R : The above is a consequence of the lanthanide contraction.

In the light of the above statements, choose the correct answer from the options given below :

Size of Bk 97 3 + ion is less than that of Np 93 3 + due to actinide contraction. As we know that in a period from left to right ionic radius decreases and in actinide series it is due to actinide contraction.
