Across
  1. 4. all elements located in Group 2 on the periodic table
  2. 6. all elements located in Group 17 on the periodic table; have high electronegativities
  3. 9. the energy required to REMOVE one electron from an atom of an element; measured in kJ/mol
  4. 12. metals are malleable (can be hammered into thin sheets and bent), ductile (can be drawn into wire), have luster (shine), and conduct electricity; metals tend to lose electrons; all metals have a “sea of mobile valence electrons”
  5. 13. elements that have all four properties/characteristics of a metal; located under/to the left of the staircase, except for Hydrogen (H)
  6. 14. have no definite shape and fill their container; at STP this includes H, N, O, F, Cl, & all of group 18 (the noble gases)
  7. 15. vertical columns on periodic table
  8. 17. horizontal rows on periodic table
  9. 18. the radius of an atom; measured in pm (picometers)
  10. 19. nonmetals are NOT malleable (shatter upon being hit with a hammer), NOT ductile, do NOT have luster (dull), and do NOT conduct electricity
  11. 20. a measure of the relative tendency of an atom of an element to attract or gain electrons; the “desire” to gain electrons; electronegativity is based on a scale from 0.0-4.0
  12. 22. elements that have two properties/characteristics of metals; located along the “staircase,” except for aluminum (Al)
  13. 23. cyclic; repeating pattern/cycle
Down
  1. 1. any of the three phases in which an element can exist; solid (s), liquid (l), gas (g)
  2. 2. elements with similar properties; group 1, 2, 17, and 18 on periodic table
  3. 3. take the shape of their container and have definite volume; only 2 elements exist as liquids at STP: Br, and Hg
  4. 5. the tendency for an atom of a given element to gain or lose electrons when interacting with an atom of another element
  5. 7. have definite shape and definite volume; most elements are solids at STP
  6. 8. elements of the periodic table are periodic functions of their atomic number
  7. 10. all elements located in Group 18 on the periodic table; inert (do not tend to react with atoms of other elements); have a full valence shell
  8. 11. all elements located in Group 1 on the periodic table except hydrogen; contains the most reactive metals
  9. 16. elements that have zero or one property/characteristic of a metal; located above/to the right of the staircase
  10. 21. full valence shell; 8 electrons, except for period 1 elements
