Naming Molecular Compounds
... We have already learned that binary = 2, therefore a binary molecular compound is a molecular compound containing only 2 elements. Names for binary molecular compounds have two parts. Three rules help name them: The first element is usually farthest to the left on the periodic table of the ele ...
