  1. 2. An atom or molecule that has gained or lost one or more electrons, resulting in a positive (cation) or negative (anion) charge.
  2. 4. Metals lose electrons and form this type of ion
  3. 5. Property of Noble Gasses, a full valence shell of 8 valence electrons and the reason they do NOT bond
  4. 6. Elements that are usually poor conductors of heat and electricity, brittle in solid form, and found on the right side of the periodic table
  5. 10. Type of Electrons in the outermost shell of an atom that determine its chemical behavior and bonding characteristics.
  6. 11. A combination of two or more substances that retain their individual properties and can be separated by physical means
  7. 14. The distance from the nucleus of an atom to the outermost shell of electrons
  8. 16. Which element has a great ionization energy: Chromium or Tin?
  9. 17. The number of protons in the nucleus of an atom, which defines the element.

Down
  1. 1. A measure of an atom's ability to attract and hold onto electrons in a chemical bond
  2. 2. Energy The energy required to remove electrons from gaseous atoms.
  3. 3. Elements that have properties intermediate between metals and nonmetals; they are located along the staircase line on the periodic table
  4. 7. Two different forms of the same element with different crystal structure and different properties.
  5. 8. Nonmetals gain electrons and form this type of ion
  6. 9. Elements that are typically shiny, good conductors of heat and electricity, malleable, and ductile; found on the left side of the periodic table.
