  1. 4. An element that is typically dense, solid, ductile, malleable, highly conductive, and chemically receive, especially in the presence of nonmetal elements. Metals are located on the left end of the periodic table
  2. 5. An element with characteristics between those of metals and nonmetals; also called semiconductors; located between metals and nonmetals on the periodic table
  3. 7. An element in Group 1 of the periodic table, having one valence electron that it can easily lose to form a 1+ cation, making it extremely reactive; the most reactive of all the metals.
  4. 8. An element in group 17 of the periodic table having seven valence electrons. It easily gains an electron, forming an 1- anion, which causes it to be highly reactive.
  5. 10. A row in the periodic table of elements
Down
  1. 1. The law that states that the properties of the elements vary with their atomic numbers in a regular, repeated pattern
  2. 2. A table of the chemical elements arranged to display their periodic properties in relation to their atomic numbers
  3. 3. Any electron in the outermost energy level of a neutral atom. Unpaired valence electrons are usually involved in chemical bonding
  4. 6. A column of elements in the periodic table having similar valence electron arrangement, resulting in similar chemical properties; also known as a group
  5. 9. See family
