Question 2 A hydrogen atom is in the n = 55 state. (a) Calculate the radius of the orbit for this state. (b) Calculate the change in energy for a transition from the n = 55 state to the n = 56 state. (c) Calculate the wavelength of the photon that is absorbed in the transition in (b).

An electron in an excited energy state of the Hydrogen atom has an energy En = 0.85 eV which is 12.75 eV above the ground state. What is the radius rn of the electron’s orbit? Select one: a. 2.12 angstroms b. 8.47 angstroms c. 13.23 angstroms d. 4.77 angstroms

2. Consider an electron in a hydrogen atom that is transitioning from the n = 2 to the n = 6 level.What is the wavelength (in nm) of the photon associated with this transition?

Chapter 39, Problem 044 A hydrogen atom in a state having a binding energy (the energy required to remove an electron) of -1.51 eV makes a transition to a state with an excitation energy (the difference between the energy of the state and that of the ground state) of 10.200 eV. (a) What is the energy of the photon emitted as a result of the transition? What are the (b) higher quantum number and (c) lower quantum number of the transition producing this emission? Use -13.60 eV as the binding energy of an electron in the ground state. (a) Number Units (b) Number Units (c) Number Units
