Across
  1. 2. Atoms that contain the same number of protons with a different number of neutrons
  2. 7. A form of energy; always flows from high temperatures to low temperatures
  3. 8. Molecules that have the same molecular formula but different structures and thus different properties
  4. 9. The threshold energy that must be overcome in order to produce products in a chemical reaction
  5. 10. Property of a system relating to its heat flow
  6. 12. The energy change associated with the addition of an electron to a gaseous atom or ion
  7. 14. Energy associated with motion
  8. 15. principle As electrons fill orbitals, they must fill the lowest energy orbital available first
  9. 16. The energy required to break a given chemical bond
  10. 17. Measures the amount of randomness, disorder, or chaos in a system
Down
  1. 1. The amount of energy required to remove an electron from a gaseous atom or ion
  2. 3. The ability of an atom to attract electrons to itself in a shared bond
  3. 4. Energy associated with position or stored energy
  4. 5. The energy released when gaseous ions form a crystal lattice
  5. 6. Common name for H2O
  6. 11. Electrons must separately fill equal energy orbitals (i.e. 3 separate p orbitals) before pairing in a single orbital
  7. 13. Related to amount of work a system may produce
