  1. 2. a law stating that the elements, when listed in order of their atomic numbers (originally, atomic weights), fall into recurring groups, so that elements with similar properties occur at regular intervals.
  2. 3. the horizontal rows on a periodic table
  3. 5. minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule.
  4. 7. Dull, poor conductors of heat and electricity, when solid they are brittle and unnmalleable.
  5. 8. is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond.
  6. 9. elements in the last group on the periodic table.
  7. 11. distance between the nucleus and valance electron of an element
Down
  1. 1. Semi conducting,some shiny,some dull,somewhat malleable and ductile.
  2. 4. the distance between the nucleus of an ion and the outermost shell of the ion
  3. 6. shiny,good conductors of electricity,malleable, ductile.
