Across
  1. 4. a molecule in which the centroid of the positive charges is different from the centroid of the negative charges.
  2. 6. capable of being dissolved
  3. 7. an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion) which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion) which is created by an electron gain and is attracted to the anode. The valence of an ion is equal to the number of electrons lost or gained and is indicated by a plus sign for cations and a minus sign for anions, thus: Na + , Cl−, Ca ++ , S = .
  4. 8. Also called electrolytic conductor. a conducting medium in which the flow of current is accompanied by the movement of matter in the form of ions.
  5. 11. the measure of the amount of electrical current a material can carry
  6. 18. Formal charge is the difference between the number of valence electrons of each atom and the number of electrons the atom is associated with. Formal charge assumes any shared electrons are equally shared between the two bonded atoms.
  7. 19. the quality or property of being soluble; relative capability of being dissolved.
Down
  1. 1. electric charge
  2. 2. having a surplus of electrons; having a lower electric potential
  3. 3. to drive or force back
  4. 5. having a deficiency of electrons; having a higher electric potential
  5. 9. The temperature at which a solid substance melts or fuses.
  6. 10. the temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid, equal to 212°F (100°C) for water at sea level.
  7. 12. A molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electrons.
  8. 13. A molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electrons.
  9. 14. to make a solution pass into a solute
  10. 15. a substance, body, or device that readily conducts heat, electricity, sound, etc.: Copper is a good conductor of electricity.
  11. 16. A compound formed by ions bonding together through electrostatic forces.
  12. 17. a material of such low conductivity that the flow of current through it is negligible.
