Across
  1. 3. Nonmetals are located on the right side of the periodic table. Nonmetals commonly form bonds with metals.
  2. 6. they display properties of both metals and nonmetals. Metalloids can be found in 4 different families along the stair-step line on the periodic table. These elements are considered semi-conductors and often form weak bonds.
  3. 7. The 7 horizontal (across) rows of elements in the periodic table One common characteristic is how many electron energy levels these atoms have. 1st row has 1 energy level. 2nd row has 2 energy levels.
Down
  1. 1. The 18 vertical (up/down) columns of elements in the periodic table. One common characteristic is how these atoms form compounds since they all have the same number of outer electrons.
  2. 2. Metals are located on the left side of the periodic table. Metals commonly form bonds with nonmetals to make compounds.
  3. 4. Elements in family 17. These nonmetals have 7 outer electrons. The word halogen means “salt former.” They are very reactive elements.
  4. 5. Elements in family 18. These nonmetals have full outer energy levels. These elements are very stable and do not naturally form compounds with other elements. These nonmetals are gases at room temperature.
  5. 6. A combination of two or more materials that are NOT chemically combined. There are several different categories of mixtures. (solutions, colloids, suspensions)
