Across
  1. 4. negative atoms
  2. 5. tells you how many protons are in an element
  3. 7. A charged atom, due to gaining or losing electrons
  4. 12. tells you the overall number of protons and neutrons
  5. 13. "sea" of electrons forms in this type of bond
  6. 14. outermost orbit of electrons, often having a maximum of 8
  7. 15. elements that don't want anything to do with other elements; do not form bonds easily
  8. 17. unequal sharing of electrons between atoms
Down
  1. 1. the row of the periodic table
  2. 2. elements that always form +1 charge
  3. 3. two charged atoms coming together
  4. 6. sharing of electrons between atoms
  5. 8. elements that always form -1 charge
  6. 9. positive atoms
  7. 10. How we determine charge; atoms will lose electrons to 0 or gain electrons to 8
  8. 11. groups of atoms coming together
  9. 16. elements that share the same one of these have very similar properties
