A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 3 excited state. The ion returns to the ground state by emitting several photons. What is the wavelength of the highest energy photon?
A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 6 excited state. The ion returns to the ground state by emitting FIVE photons ONLY. What is the wavelength of the second-highest energy photon?

Chapter 30, Problem 59 The Bohr model can be applied to singly ionized helium He+ (Z=2). Using the model, consider the series of lines that is produced when the electron makes a transistion from higher energy levels into the nf = 4 level. Some of the lines in the series lie in the visible region of the spectrum (380 nm - 750 nm). What are the (a) minimum value and (b) maximum value of ni for the energy levels from...
(b) If the wavelength of a photon emitted during the α-transition of the Paschen series is 1.875 um, determine the energy of the photon. 2 marks) The equation for the radius of the Bohr orbits in an atom is (c) y(4760) . If a singly ionised helium atom (He+,2-2) has only one electron in where orbit about the nucleus, what is the radius of the ion when in the second excited state? (3 marks) (b) If the wavelength of a...
The Bohr model can be applied to singly ionized helium He+ (Z = 2). Using this model, consider the series of lines that is produced when the electron makes a transition from higher energy levels into the = 4 level. Some of the lines in this series lie in the visible region of the spectrum (380−750 nm). What are the values of for the energy levels from which the electron makes the transitions corresponding to these lines? We were unable...
A helium atom has two electrons, let us call them electron 1 and 2. Suppose electron 1 is in the ground state and electron 2 is in the first excited state. 1. Calculate the minimum energies (in eV) of photons needed to eject each electron out of the atom. [5 points) 2. Draw an energy level diagram for a helium atom and indicate the transitions in part 1. You do not need to calculate the energies of various energy levels....
