$Fr$

Vedclass · Answer

(A) The electronic configuration of Francium $(Fr)$ is $[Rn] 7s^1$.When it loses one electron to form a $+1$ oxidation state,it becomes $Fr^+ = [Rn]$.Since $[Rn]$ is the electronic configuration of the noble gas Radon,$Fr$ achieves a noble gas configuration in the $+1$ state.Other elements like $Ca$,$Mg$,and $Sr$ are alkaline earth metals and typically form $+2$ oxidation states to achieve noble gas configurations.

Which among the following elements develops noble gas configuration in $+1$ state?
