Across
  1. 6. is usually the compound’s empirical formula for ionic compounds.
  2. 8. is often useful to know the percentage by mass of a particular element in a chemical compound.
  3. 14. polyatomic ions that contain oxygen.
  4. 15. is numerically equal to its molar mass, so a compound’s molecular formula can also be found given the compound’s empirical formula and its molar mass.
  5. 17. is a certain type of molecular compound.
  6. 18. involves combining the names of the compound’s positive and negative ions.
  7. 19. consists of the symbols for the elements combined in a compound, with
  8. 21. indicates the relative number of atoms of each kind in a chemical compound.
  9. 22. An ionic compound composed of a cation and the anion from an acid
  10. 23. can be assigned to atoms in order to keep track of electron distributions in molecular as well as ionic compounds.
  11. 24. To distinguish the ions formed by such elements.
Down
  1. 1. is the actual formula of a molecular compound.
  2. 2. showing the smallest whole-number mole ratio of the different atoms in the compound.
  3. 3. Shows how the atoms in each ion are bonded together.
  4. 4. has an oxidation number of +1 in all compounds containing elements that are more electronegative than it but has an oxidation number of –1 with metals.
  5. 5. are acids that consist of two elements,usually hydrogen and a halogen.
  6. 7. numerically equal to its formula mass.
  7. 9. compounds composed of two elements
  8. 10. The mass of a water molecule
  9. 11. are acids that contain hydrogen, oxygen,and a third element (usually a nonmetal).
  10. 12. is the sum of the average atomic masses of all atoms represented in its formula.
  11. 13. are bound together in a group and carry a characteristic charge.
  12. 16. usually has an oxidation number of –2.
  13. 20. has an oxidation number of –1 in all its compounds because it is the most electronegative element.
