His model of the hydrogen atom led to an accurate calculation of the wavelengths of light emitted by an excited hydrogen atom.

What is a possible quantum number set for an electron in the 3s orbital of a magnesium atom

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
