Short Answer
22.1 The Structure of the Atom
Why do Bohr’s calculations for electron energies not work for all atoms?
- In atoms with more than one electron is an atomic shell, the electrons will interact. That requires a more complex formula than Bohr’s calculations accounted for.
- In atoms with 10 or more electorns in an atomic shell, the electrons will interact. That requires a more complex formula than Bohr’s calculations accounted for.
- In atoms with more than one electron in an atomic shell, the electrons will not interact. That requires a more complex formula than Bohr’s calculations accounted for.

- no
- yes
22.3 Half Life and Radiometric Dating
- The radioactive activity decreases exponentially.
- The radioactive activity undergoes linear decay.
- The radioactive activity undergoes logarithmic decay.
- The radioactive activity will not change with time.
22.4 Nuclear Fission and Fusion
- Heavy nuclei require more neutrons to achieve stability.
- Heavy nuclei require more neutrons to balance charge.
- Light nuclei require more neutrons to achieve stability.
- Light nuclei require more neutrons to balance charge.
