  1. 4. Cloud Location of electrons(outside of nucleus)
  2. 9. An element that tends to gain electrons in a bond and is a good insulator
  3. 11. A measure of how hard an atom pulls on bonding electrons
  4. 13. The first person credited for arranging elements in order of properties on a periodic table
  5. 14. A 3D area within a sublevel where there is a high probability of finding an electron
  6. 15. Rule Empty orbitals fill before electrons begin pairing up
Down
  1. 1. Law The physical and chemical properties of an element are a function of their atomic number
  2. 2. An element that tends to loose electrons in a bond and is a good conductor of heat and electricity
  3. 3. Radius Determines the size of an atom
  4. 5. The minimum amount of energy that an electron gains/loses when it changes energy levels
  5. 6. Electrons The electrons in the outer most energy level
  6. 7. Numbers Set of values that describe the state of an electron
  7. 8. Effect The effect of the positive nucleus on its outer electrons is reduced by inner electrons
