Assertion is correct,Reason is wrong.

Vedclass · Answer

(C) Actinides exhibit a larger number of oxidation states than lanthanides because the energy gap between the $5f$,$6d$,and $7s$ subshells is very small. This allows the electrons to be easily excited to higher energy levels,leading to variable oxidation states. In contrast,the energy gap between $4f$,$5d$,and $6s$ subshells in lanthanides is relatively larger. Therefore,the Assertion is correct,but the Reason is incorrect because the energy gap is small,not large. Thus,the correct option is $(C)$.

Choose the correct option regarding the following.
Assertion: Actinides exhibit a larger number of oxidation states than lanthanides.
Reason: There is a large energy gap between $5f$,$6d$ and $7s$ sub-shells.
