Across
  1. 4. The most reactive column of elements (think group 17.)
  2. 5. This can be positive or negative and this pattern stretches across the periodic table from + to neutral.
  3. 7. The horizontal rows on the periodic table.
  4. 8. The right side of the periodic table is this. They’re not conductors of electricity.
  5. 11. The first column in the table. They are highly reactive.
  6. 13. The electrons on the outer level of the electron shell are called this.
  7. 14. The second column in the table. Still highly reactive but less than the first column.
  8. 15. The creator of the first and most recognized periodic table.
Down
  1. 1. The vertical columns on the periodic table.
  2. 2. This is what changes when you go down a column on the periodic table.This property increases.
  3. 3. Semiconductors of electricity. These few elements fall near the staircase on the periodic table.
  4. 6. The middle part of the periodic table is this(think groups 3-12.)
  5. 9. Most elements on the periodic table are this. These elements are excellent conductors of electricity.
  6. 10. The number at the top right of an element that indicates how many protons it contains.
  7. 12. The column of elements with full outer electron shells and little to no reactivity (think group 18.)
