Vedclass · Answer

(A) In a multi-electron atom,the energy of an orbital depends on both the principal quantum number $(n)$ and the azimuthal quantum number $(l)$.Orbitals with the same $n$ and $l$ values are degenerate (have the same energy) in the absence of an external field.Analyzing the given orbitals:$(a) n=1, l=0$ $(1s)$$(b) n=3, l=0$ $(3s)$$(c) n=2, l=1$ $(2p)$$(d) n=3, l=2$ $(3d)$$(e) n=3, l=2$ $(3d)$Comparing the sets,orbitals $(d)$ and $(e)$ both have $n=3$ and $l=2$,meaning they are both $3d$ orbitals.Therefore,they have the same energy.

In a multi-electron atom,which of the following orbitals have the same energy in the absence of magnetic and electric fields? $(a) n = 1, l = 0, m = 0, (b) n = 3, l = 0, m = 0, (c) n = 2, l = 1, m = 1, (d) n = 3, l = 2, m = 1, (e) n = 3, l = 2, m = 0$
