a. Write the metal first, then the nonmetal. b. Write out the name of the symbol. Find the
elements’ names on Reffy, Table S (pp. 10-11). c. Make the second element end in ide.

a. If you are given ‘Cl’ and ‘Na’, write NaCl.
b. The elements are sodium and chlorine.
c. Change the ending of the second element to get Sodium chloride.
