Across
  1. 2. the width of the atom, increases from top to bottom of a group and decreases from left to right of a period
  2. 5. The energy required to remove an electron from an atom or molecule, increases up a group and across a period
  3. 7. fill in the d-orbital, have several different oxidation states
  4. 9. The measurement of an atom's ability to attract shared electrons, increases across a period, decreases down a group.
  5. 10. the effect that decreases the nucleus' attractive forces, remains constant across a period and increases down a group
Down
  1. 1. this determines how much an electron is attracted to the nucleus, increases across a period and increases down a group
  2. 3. Located in group 2 (There is a dash between the first two words)
  3. 4. Really reactive, located in group 7
  4. 6. the most reactive metal group, located in group 1
  5. 8. These gases are unreactive
  6. 11. The energy change that is a result of adding an electron to an atom in the gaseous state. Increases across a group and decreases down a group.
