  1. 3. A negatively charged ion; they take the -ide suffix on the name of the atom from which they came.
  2. 6. A __ bond is one in quich a shared pair of valence electrons hold atoms together in __ (same word) compounds.
  3. 8. __ have a tendency to "lose" electrons in ionic bonding.
  4. 9. A positively charged ion; they take the same name as the atom from which they came.
  5. 10. A measure of how strongly an atom attracts extra electrons to itself.
  6. 11. ___ electrons are in the highest energy level and largely determine an element's chemical properties.

  1. 1. __ energy is the amount of energy needed to take an electron away from an atom.
  2. 2. ___ gases are group 8A elements with full outer energy levels.
  3. 4. The __ rule refers to group 1A - 8A elements (except H & He) having "full" outer energy levels when they have 8 valence electrons.
  4. 5. Atoms that have gained or lost one or more electrons, becoming electrically charged.
  5. 7. A characteristic of atoms that varies regularly across the periodic table.
