Vedclass · Answer

(C) According to the Aufbau principle,the energy of an orbital is determined by the $(n + l)$ rule.For $4s$: $n = 4, l = 0$,so $(n + l) = 4 + 0 = 4$.For $3d$: $n = 3, l = 2$,so $(n + l) = 3 + 2 = 5$.For $4p$: $n = 4, l = 1$,so $(n + l) = 4 + 1 = 5$.Since $4s$ has the lowest $(n + l)$ value,it has the lowest energy.Between $3d$ and $4p$,both have $(n + l) = 5$,but $3d$ has a lower $n$ value $(3 Thus,the correct order is $4s < 3d < 4p$.

According to the Aufbau principle,what is the correct order of energy for $3d$,$4s$,and $4p$ orbitals?
