An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. Classify the statements about this absorption and emission process as true or false. True On average, the electron is closer to the nucleus in the n = 4 state than in the n = 1 state. The wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of...

A hydrogen electron, initially in its second excited state (n=3), jumps down to the ground state n=1. The energy of n=1 state is -13.6 eV. A) What is the energy of the photon emitted from this jumping down process? ( I got 12.08889eV) B) Is this emitted photon energetic enough to create photoelectrons from Ni( Ni working function is 5 eV)?

Show that the deuteron has no bound excited states by estimating the excited state energy and comparing it to the potential well. Consider two cases for the excited state: a) higher order radial eigenfunctions, b) non-zero angular momentum. c) If the nuclear force had a longer range R >R0 we could possibly have excited states. What would be the minimum and maximum values of R∗ so that there could be an excited state with l = 1 but no excited...
