Consider an electron in the N shell. (b) What is the largest orbital angular momentum it could have? Express your answers in terms of U and in SI units

An electron and a positron are moving toward each other and each has speed 0.500c in the lab frame. (a) What is the kinetic energy of each particle?

Model a hydrogen atom as an electron in a cubical box with side length L. Set the value of L so that the volume of the box equals the volume of a sphere of radius a = 5.29 * 10-11 m, the Bohr radius. Calculate the energy separation between the ground and first excited levels, and compare the result to this energy separation calculated from the Bohr model.

A photon is emitted when an electron in a threedimensional cubical box of side length 8.00 * 10-11 m makes a transition from the nX = 2, nY = 2, nZ = 1 state to the nX = 1, nY = 1, nZ = 1 state. What is the wavelength of this photon?

Consider an electron in the N shell. (a) What is the smallest orbital angular momentum it could have?

Consider an electron in the N shell. (c) What is the largest orbital angular momentum this electron could have in any chosen direction? Express your answers in terms of U and in SI units.

Consider an electron in the N shell. (d) What is the largest spin angular momentum this electron could have in any chosen direction? Express your answers in terms of U and in SI units.

The orbital angular momentum of an electron has a magnitude of 4.716 * 10-34 kg # m2>s. What is the angular momentum quantum number l for this electron?

Calculate, in units of U, the magnitude of the maximum orbital angular momentum for an electron in a hydrogen atom for states with a principal quantum number of 2, 20, and 200. Compare each with the value of nU postulated in the Bohr model. What trend do you see?
