Vedclass · Answer

(C) According to the $(n+l)$ rule,the energy of an orbital is determined by the sum of the principal quantum number $(n)$ and the azimuthal quantum number $(l)$.For $5p$ orbital: $n=5, l=1$,so $(n+l) = 5+1 = 6$.For $4f$ orbital: $n=4, l=3$,so $(n+l) = 4+3 = 7$.For $5d$ orbital: $n=5, l=2$,so $(n+l) = 5+2 = 7$.For $6s$ orbital: $n=6, l=0$,so $(n+l) = 6+0 = 6$.After the $4d$ orbital is filled,the electrons fill the $5p$ orbital before moving to the $6s$ orbital. Therefore,the next orbital to be filled after $4d$ is $5p$.

List-$I$ (Quantum numbers)	List-$II$ (Orbital)
$A$. $n = 2, l = 1$	$I$. $3d$
$B$. $n = 4, l = 0$	$II$. $2p$
$C$. $n = 5, l = 3$	$III$. $4s$
$D$. $n = 3, l = 2$	$IV$. $5f$

When the $4d$ orbital is complete,the newly entering electron goes into which orbital?
