E) none of the above 5. For a one electron atom, which of the following transitions does the light emitted have the lowest frequency? A) n = 4 to n = 3 B) n = 4 to n = 2 C) n = 4 to n = 1 D) n = 3 to n = 2 E) n = 2 to n = 1 6. Which of the following statements is true? A) The krypton 1 s orbital is smaller than the helium 1 s orbital because krypton's nuclear charge draws the electrons closer. B) The krypton 1 s orbital is larger than the helium 1 s orbital because krypton contains more electrons. C) The krypton 1 s orbital is smaller than the helium 1 s orbital because krypton's p and d orbitals crowd the s orbitals. D)
