How far from the nucleus in angstroms (1 angstrom = 1 10–10 m) is the electron in a hydrogen atom if it has an energy of –8.7210–20 J? The radius of the orbital (r) = n2 a0/Z (n is the quantum number of an orbital, a0 is the Bohr radius with a value of 5.292×10−11 m, Z is the nuclear charge). Hint: figure out n first and the radius of the orbital is the distance.

Using the Bohr model, determine the lowest possible energy, in joules, for the electron in the Li2+ ion. En = -kZ2/n2 (k = 2.179×10–18 J, n is the quantum number of an orbital, Z is the nuclear charge; this equation applies to an atom with only one electron; please note that the nuclear charge is different from the atom charge)

The electron volt (eV) is a convenient unit of energy for expressing atomic-scale energies. It is the amount of energy that an electron gains when subjected to a potential of 1 volt;1 eV = 1.602 ✕ 10−19 J. Using the Bohr model, determine the energy, in electron volts, of the photon produced when an electron in a hydrogen atom moves from the orbit with n = 4 to the orbit with n = 2. (Assume that the Bohr constant and...

2. In the derivation of the energy levels in the hydrogen atom one commonly assumes that the nucleus is a point charge. However, in reality the size of the nucleus is of the order of Im = 10-15m. Since this is very much smaller than the typical distance of the electron from the nucleus, which is of the order of a0-0.5A = 0.5 × 10-10m, the finite size of the nucleus can be taken into account perturbatively. (a) Assume that...
