  1. 3. A measure of how hard an atom pulls on BONDING electrons
  2. 5. An element that tends to gain electrons in a bond and is a good insulator.
  3. 7. Organized space within an energy level, named s,p,d,and f. These shapes have associated shapes.
  4. 9. The amount of energy required to remove the most loosely held electron from an atom.
  5. 10. Determines the size of an atom.
  6. 11. A 3-D area within a sublevel where there is a high probability of finding an electron.
  7. 13. Empty orbitals fill before electrons are paired up.
  8. 14. The first person credited for arranging elements in order of properties on a periodic table
Down
  1. 1. The electrons in the outermost energy level, only 8 possible must be in the highest energy level sublevel sandp. These are the first electrons involved in bonding.
  2. 2. An element that tends to lose electrons in a bond and is a good conductor of heat and electricity.
  3. 4. An element that has some characteristics of metals and some nonmetals.
  4. 6. The physical and chemical properties of an element are a function of their atomic number.
  5. 7. The effect of the positive nucleus on its outer electrons is reduced (shielded) by inner electrons.
  6. 8. Location of electrons (outside of nucleus)
  7. 12. The minimum amount of energy that an electron gains/losses when it changes energy levels.
