  1. 2. the number of wave cycles or crests that pass through a stationary point in one second
  2. 3. an integer that specifies the energy of an orbital
  3. 5. the longest wavelength and least energetic form of electromagnetic radiation
  4. 10. the shortest-wavelength, most energetic form of electromagnetic radiation
  5. 11. a type of energy that travels through space at a constant speed
  6. 13. a model for the atom in which electrons travel around the nucleus in circular orbits at specific, fixed distances from the nucleus
  7. 14. the region around the nucleus of an atom where an electron is most likely to be found

Down
  1. 1. the distance between adjacent wave crests in a wave
  2. 3. the foundation of modern chemistry; explains how electrons exist in atoms and how they affect the chemical and physical properties of elements
  3. 4. the fraction of the electromagnetic spectrum between visible light and microwaves
  4. 6. next to the gamma rays on the electromagnetic spectrum. Longer in wavelength and lower in energy than gamma rays. Most commonly known for their medical use.
