Exam 39: Quantum Structure of Atoms, Molecules, and Solids

An ensemble of excited atoms emits light at a wavelength of 496 nm. The energy difference between the two energy levels involved in the emission of the light is

The resistivity of a pure semiconductor

The energy of the stationary states of the hydrogen atom primarily depends on

If the principal quantum number's value is n = 3, the value of m that is not allowed is

Observed similarities of the chemical properties in the elements listed in each column of the periodic table are due to

An energy gap between the valence band and the conduction band is 3.5 eV in a particular solid. The maximum wavelength of a photon that can excite a transition from the top of the valence band to the conduction band is

If $l$ = 3, the value for n that is not permitted is

Given that n = 2 for an electron configuration, the following stationary state is not permitted:

A diode is operated in the forward-biased mode. An increase in the bias voltage will

The ionization energy for the hydrogen atom is 13.6 eV. The wavelength of the photon emitted when the hydrogen makes a transition from n = 3 to n = 1 is

A diode and a 100- $\Omega$ resistor are connected in series with a 5.0-V power supply. The diode is connected so that it is reversed-biased. The voltage drop across the diode is
