PFC2 Chapter 10 Section 2 Guided Reading
1. What is a spectrum?
2. A ________________ spreads light into its own individual colors.
3. Different colors of light have different amounts of _________________.
4. Danish physicist Neils Bohr proposed the concept of _________________
_________________ to explain the spectrum.
5. When an electron in an atom “jumps” from a higher energy level to a lower energy
level, energy in the form of _________________ is released.
6. ______________ ______________ says that when a particle, such as an electron, is
confined to a small space inside an atom, the energy, momentum, and other variables of
the particle become quantized and can only have specific values.
7. The quantum model of the atom describes the electron as a “fuzzy” cloud of negative
charge called a ______________ ______________ rather than as a particle moving
around the nucleus.
8. State the Pauli exclusion principle.
9. What is Heisenberg’s “uncertainty principle?”
10. The smallest quantity of light energy is called a _________________.
11. Using Figure 10.14, explain what happens when you bounce a photon off an electron.
12. The science of describing the chance that an event or event will occur is called
_________________.
13. Quantum theory uses probability to predict how likely it is that an electron will be found
at various distances from a nucleus. This probability is described mathematically by a
_________________ function.
