An electrons in a hydrogen atom finds itself in the fourth energy leve

1.	An electrons in a hydrogen atom finds itself in the fourth energy level. (i) Write down a list of the orbits that it might be in. (ii) Can it be in all of these orbitals at once? (iii) Can you tell which orbital it is in ?
Answer» Correct Answer - (i) `4s, 4P, 4d, 4f` (ii) No, it will only be in one of them. (iii) No. For the hydrogen atom all orbitals with the same principal quantum number have the same energy (they are degenerate). (i) `4s, 4P, 4d, 4f` (ii) No, it will only be in one of them. (iii) No. For the hydrogen atom, all orbitals with the same principal quantum number have the same energy (they are degenerate). (i) `4s, 4P, 4d, 4f`
