Vedclass · Answer

(D) The general electronic configuration of actinoids is $(5f)^{0-14} (6d)^{0-2} (7s)^2$.Since all actinoids have two electrons in the $7s$ orbital,statement $(a)$ is False $(F)$ because they do not have $7s^1$.Statement $(b)$ is False $(F)$ because they do not have $7s^0$.Statement $(c)$ is False $(F)$ because they have two electrons in the $7s$ orbital.Therefore,the correct sequence is $(a) F, (b) F, (c) F$.

Determine whether the following statements are True $(T)$ or False $(F)$:
$(a)$ All actinoid elements have a $7s^1$ configuration.
$(b)$ All actinoid elements have a $7s^0$ configuration.
$(c)$ There are no electrons in the $7s$ orbital of actinoids.
