A hydrogen atom in the ground state absorbs a 13.32-eV photon. To what level is the electron promoted? (The ionization energy of hydrogen is 13.6 eV).   a. n = 6   b. n = 5   c. n = 10   d. ​n = 11   e. n = 7
1. With what kind of “light” (e-m radiation) can we excite electrons to very high energy states, from which they will fall down in several steps – thereby making a material fluoresce in visible light?    a. microwaves. b. sub-millimeter waves.  c. radio waves.  d. IR.  e. UV.    2. Electrons inside elements can be in certain, well-defined excited states (quantum levels). When they leave such a state to a lower energy state, the frequency f of the “light” (electromagnetic radiation) emitted is related to the energy difference ΔE between such two states as:    a.an undefined quantity.  b. the same as a black-body emitter. c. the same as a gravitational field.  d. ΔE = h · f , where h is Planck’s constant. e. related via the equation c = c2   3.   About a decade later, using his oil droplet experiment, Millikan was able to find the smallest possible charge on such droplets, which he interpreted as the charge of a single electron. With that and the m/e ratio above, he was…
Which of the following principal levels contains / (angular momentum quantum number) = 3? A. n = 2 level B. both n = 3 and n = 4 levels C. n = 3 level D. n = 4 level How many orbitals are contained in the n = 3 principal number of a given atom? What is the value of the angular momentum quantum number of a d orbital?
