4) Consider the diagram of hydrogen below. This diagram shows de Broglie’s explanation of the Bohr model: an electron orbits a proton as a matter wave. Since this is a standing wave, only specific wavelengths and thus orbits are allowed.
a) What is the quantum number n of the energy level shown on the lefthand side of the diagram? Explain.
b) On the right part of the diagram, draw the electron wave for the state one value below that of part a)
c) Using the leftmost diagram, find a formula that relates the
wavelength of the electron in terms of the orbital radius
r.

Question 4 of 5 Map According to de Broglie's explanation of the Bohr atom, each possible electron orbit in a hydrogen atom corresponds to a particular standing wave pattern. In the figure at right is shown a diagram of an atom with two different electron orbits which have been "cut and unwrapped" to better show the electron waves. Suppose the standing wave pattern of the inner orbit is given in the figure. Sort the patterns below by whether or not...

Determine the circumference of the second Bohr orbit of the Hydrogen atom. Use this to determine the wavelength of the electron in this orbit; the electron's wave must consist of an integral number of wavelengths about its orbit's circumference (Why?). orbit circumference = n wavelength Finally, determine the velocity v of the electron in this orbit using de Broglie's prescription for the wavelength of matter waves. wavelength = h / mv What percentage of the speed of light is this...

please Solve part D and E!!!!! PLEASE AND THANK YOU
acc1 Our discussion of the Bohr model of the hydrogen atom was non-relativistic throughout, which was justified because the velocity of the electron in the nth state of Bohr's hydrogen atom was v= (1) 1377 where a = 1 is the fine-structure constant, and qe is the electron charge, ħ is (the reduced) Planck's constant, and c is the speed of light. Clearly, as n grows, the speed does become...

Tl 6. (4 pts) We calculated Ahf for the ground state Hydrogen atom, but now let us consider Hht for the ground state of the deuterium atom. The basic idea is the same: Here the matrix representation of S is the same, since it represents the spin operator for the spin- electron, but that of 7 is different because the deuteron is a spin-1 particle (neutron+proton) whose spin has 3 possible values for the magnetic quantum number. Also, we must...
