Vedclass · Answer

(B) The given electronic configuration is $[Rn]\, 7s^2\, 5f^3\, 6d^1$.$1$. The highest principal quantum number $(n)$ is $7$,which indicates that the element belongs to Period $7$.$2$. The last electron enters the $5f$ orbital,which classifies the element as an $f$-block element (Actinoid series).$3$. All $f$-block elements belong to Group $3$ (or $III\, B$ in the older $IUPAC$ notation).Therefore,the element belongs to Period $7$,Group $3$ $(III\, B)$,and $f$-block.

An element with electronic configuration $[Rn]\, 7s^2\, 5f^3\, 6d^1$ will fall in
