Across
  1. 4. element that has the property of shiny luster, ductility, and malleability
  2. 5. element that lacks most of the properties of a metal, is not shiny, does not conduct electricity or heat well, is not malleable so it is called brittle or breakable.
  3. 6. smallest part of an element that can be identified as that element
  4. 8. able to be drawn into thin wires
  5. 9. particle that has a negative charge - located in rings outside the nucleus of an atom. You can figure out the number of electrons by looking at the atomic number of an element.
  6. 10. place in an electron cloud where an electron is most likely to be found - rings. Remember, 2-8-18-32.
  7. 12. number of protons in the nucleus of an atom. This is the same number as the number of electrons
  8. 13. elements that make up Group 17 in the periodic table
  9. 14. the way a material reflects light.
Down
  1. 1. particle that has no charge - located in the nucleus of an atom. You can figure out the number of neutrons by SUBTRACTING the atomic Mass minus the atomic number.
  2. 2. able to be hammered into different shapes
  3. 3. particle that has a positive charge - located in the nucleus of an atom. You can figure out the number of protons by looking at the atomic number of an element.
  4. 6. total mass of the protons and neutrons in an atom
  5. 7. center, or core, of an atom (where the protons and neutrons are located)
  6. 11. substance that CANNOT be chemically broken down into simpler substances
