Across
- 4. the distance between crests
- 5. a waves height from zero to crest
- 9. includes radio waves, microwaves, infared waves, visible light, ultraviolet waves, x-rays, and gamma rays
- 10. physics on an atomic scale
- 12. fixed distances from the nucleus of an atom where electrons may be found
- 14. an electron occupies the lowest energy orbital that can recieve it
- 15. the number of wave cycles to pass a given point per unit of time
- 17. lowest energy electrons are found
- 18. physics on a planetary scale
- 21. no 2 electrons in a subshell can be exactly the same; they can share orbitals but must be spinning in different directions
Down
- 1. variety of frequencies of electromagnetic radiation that are emitted by electrons as they transition from higher to lower energy levels
- 2. electrons are ejected when light shines on a metal
- 3. single packet of matter or energy
- 6. explained color changes dealing with heat by assuming that the energy changes only in small discrete units, or quanta
- 7. light quanta
- 8. show the probability of finding an electron at various locations around the nucleus
- 11. the length of each period is determined by the number of electros that can occupy the sublevels being filled in that period
- 13. the SI unit, with a special name, for frequency
- 16. orbitals of equal energy are each occupied by one electron before any orbitals are occupied by a second electron; all electrons in singly occupied orbitals must be spinning at the same rate
- 19. property on an electron that is loosely related to its spin about an axis and its angular momentum
- 20. characteristic wavelengths of electromagnetic radiation that is emitted or absorbed by an object or substance, atom, or molecule
