1. Which one of the following types of radiation has the shortest wavelength, the greatest energy, and the highest frequency? a. Ultraviolet radiation. b. Infrared radiation. C. Visible red light. d. Visible blue light. e. None, because short wavelength is associated with low energy and low frequency, not high energy and high frequency. 2. The four lines observed in the visible emission spectrum of hydrogen tell us that: a. The hydrogen molecules they came from have the formula H4. b. We could observe more lines if we had a stronger prism. C. There are four electrons in an excited hydrogen atom. d. Only certain energies are allowed for the electron in a hydrogen atom. e. The spectrum is continuous. 3. Which of the following is not determined by the principal quantum number, n, of the electron in a hydrogen atom? a. The energy of the electron. b. the minimum wavelength of the light needed to remove the electron from the atom. C. The size of the corresponding atomic orbital(s). d. The shape of the corresponding atomic orbital(s). e. All of the above are determined by n. 4. The statement that "the lowest energy configuration for an atom is the one having the maximum number of unpaired electrons allowed by the Pauli principle in a particular set of degenerate orbitals" is known as; a. the aufbau principle b. Hund's rule c. Heisenberg uncertainty principle d. the Pauli exclusion principle e. the quantum model 5.Which of the following combinations of quantum numbers is not allowed? a. n = 1, 1 = 1, m = 0, ms = ½/2 b. n = 3,1 = 0, m₁ = 0, ms = - ½ c. n = 2, 1 = 1, m = -1, ms = ½/2 d. n = 4,1 = 3, m = -2, ms = -½ e. n = 4, 1=2, mı = 0, ms = ½ 6.Atoms with greatly different electronegativity values are expected to form: a. no bonds b. covalent bonds c. triple bonds d. ionic bonds e. none of these
