Vedclass · Answer

(B) $Sc (Z = 21) 	o [Ar] 3d^1 4s^2$The $d-$block elements belonging to groups $3-12$ are known as transition elements because their physical and chemical properties are intermediate between $s-$block and $p-$block elements.The first transition series (the $3d$ series) starts with Scandium $(Z = 21)$ and ends with Zinc $(Z = 30)$.Therefore,the first transition element is Scandium.
