Across
  1. 4. the electrons in the outermost energy level of a neutral atom.
  2. 6. They have one valence electron, which they can easily lose to form a 1+ cation
  3. 8. a set of elements in the same column on the periodic table.
  4. 10. the properties of the elements vary in a periodic way with their atomic numbers.
  5. 11. the distance from the center of an atom’s nucleus to the electrons in its outermost energy level. T
  6. 12. These elements each have seven valence electrons.
  7. 14. These groups are also named for the first element in each family.
  8. 16. consists of the element’s chemical symbol surrounded by the atom’s valence electrons.
  9. 18. These elements typically have four or more valence electrons and do not exhibit the general properties of metals.
Down
  1. 1. They typically have two valence electrons, and so they form 2+ cations.
  2. 2. Almost 80% of elements are metals, which have few valence electrons.
  3. 3. They each have two valence electrons, which they tend to lose, making them 2+ cations.
  4. 5. The measure of an element’s ability to attract and hold electrons when bonded to other atoms
  5. 7. These elements have character­istics between those of metals and nonmetals.
  6. 9. a table of the chemical elements arranged in a way that displays their periodic properties in relationship to their atomic numbers.
  7. 13. The elements in this group have eight valence electrons
  8. 15. a row on the periodic table
  9. 17. a set of elements in the same column on the periodic table.
