Vedclass · Answer

(B) According to the Aufbau principle,electrons fill orbitals in the order of increasing energy,which is determined by the $(n + l)$ rule.For the given orbitals:$4s: n=4, l=0 \implies n+l = 4$$3d: n=3, l=2 \implies n+l = 5$$4p: n=4, l=1 \implies n+l = 5$$5s: n=5, l=0 \implies n+l = 5$$4d: n=4, l=2 \implies n+l = 6$Comparing the $(n+l)$ values and the $n$ values for orbitals with the same $(n+l)$,the correct order is $4s < 3d < 4p < 5s < 4d$.
