Binary Molecular
Compounds
Binary molecular compounds
consist of covalent bonds
between atoms of two different
non-metals.
1.The name of a binary molecular
compound ends in “ide”, just like
the came of a binary ionic
compound.
2. The name and the formula
usually begin with the element
that is more to the left on the
periodic table.
3. In the name, use a prefix to
directly specify the number of
atoms of each element that are
present in a molecule. Some
prefixes, and the numbers they
represent, are in the table below.
