QUESTION When an electron undergoes a transition from a higher to lower state in singly ionizedhelium, how will the energy of the emitted photon compare with the analogous transition in hydrogen?Explain. (Select all that apply.)O The transition energy will be higher in singly ionized helium.O This happens because the helium atom has more protons.O This happens because the helium nucleus is less massive.The transition energy will be lower in singly ionized helium.This happens because the helium atom has more neutrons.

The K series of the discrete spectrum of tungsten contains wavelengths of 0.0185 nm, 0.0209 nm, and 0.0215 nm. The K-shell ionization energy is 69.5 keV. Determine the ionization energies of the L, M, and N shells. Step 1 Characteristic x-rays of the K series are produced when an electron in an upper energy level of a many- electron atom drops down to fill a vacancy in the K (n = 1) shell. Assuming that the given wavelengths are the three longest wavelengths in the K series of tungsten, the transitions that produce them are from the N (n 4) shell to the K shell, from the M (n = 3) shell to the K shell, and from the L (n = 2) shell to the K shell, respectively. These transitions are shown in the energy level diagram, where 1, = 0.0185 nm, = 0.0209 nm, and 13 12 EK = 0.0215 nm. If the ionization energy of the K shell is 69.5 keV, then = -69.5 keV.

4. The energy of the atom is in part determined by the electrical potential energy of the electron interacting with the proton nucleus, and when the electron is close to the nucleus it is very tightly bound. That's why the energy is negative, and larger in magnitude the smaller n. What does this tell you about the size of the atom for large n? Explain your reasoning.
