Across
- 2. uncertainty principle- The principle that states that determining both the position and velocity of an electron or any other particle simultaneously is impossible
- 4. configuration- An outer main energy level fully occupied in most cases by eight electrons
- 8. Spectrum- an unbroken sequence of frequencies or wavelengths of electromagnetic radiation often committed by an incandescent source
- 9. Radiation The radiation associated with an electric and magnetic field
- 11. state- the lowest energy state of the quantized system
- 12. gas- one of the elements of group 18 of the periodic table; theyre non-reactive
- 13. The distance from any point on a wave to an identical point on the next wave
- 18. configuration- The arrangement of electrons in an atom
- 20. theory- the study of the structure and behavior of the atom and of subatomic particles from The View that all energy comes in tiny indivisible bundles
- 21. a unit or Quantum of light
- 23. quantum number- the quantum number that indicates the orientation of an orbital around the nucleus
- 25. the basic unit of electromagnetic energy
- 26. Exclusion Principle- the principle that states that two particles of a certain class cannot be in exactly the same energy state
Down
- 1. state- a state in which an atom has more energy than it does at its ground state
- 3. spectrum- All of the frequencies or wavelengths of electromagnetic radiation
- 5. quantum number-The quantum number that indicates the energy and orbital of an electron in an atom
- 6. quantum number- the quantum number that describes the intrinsic angular momentum of a particle
- 7. a region in an atom where there is a high probability of finding electrons
- 10. principle- the principle that states that the structure of each successive element is obtained by adding one proton to the nucleus of the atom and one electron to the lowest energy orbital that is available
- 14. spectrum- Light of several different wavelengths
- 15. rule - the rule that states that for an atom in the ground state the number of unpaired
- 16. the number of Cycles or vibrations per unit of time
- 17. effect- the emission of electrons from a material when the light of certain frequencies shines on the surface of the material
- 19. is the maximum possible, and these unpaired electrons have the same spin
- 22. momentum quantum number-The quantum number that indicates the shape of an
- 24. number- a number that specifies certain properties of electrons
