Naming Compounds
I1: Ionic Compound: Made
of a metal and a non-metal
OR
Contains a polyatomic ion
I2: First name
(cation):
Name stays
the same.
If it’s a d-block
element put
the Roman
numeral
indicating
charge
I3: Second
name
(Polyatomic
anion): The
name stays
the same if
it’s
polyatomic
C1: Covalent Compound:
Made of nonmetals
C2: Prefixes are added to
indicate the number of each
type of atom
I4: Second
name
(Monatomic
anion): The
ending is
dropped
and
changed
tom to -ide
C3: If there is
one of the first
atom, the
mono prefix is
not stated
C4: The last
atom drops its
ending and
changes to
-ide
Writing Formulas
I1: Ionic Compound: Made
of a metal and a non-metal
OR
Contains a polyatomic ion
I2: Write the symbol
for each ion, with its
charge above and to
the right. Charges
for transition
elements are given
with the Roman
numeral
I2A: If the ion
is polyatomic,
put
parentheses
around the ion,
with the
charge outside
the
parentheses
C1: Covalent Compound:
Made of nonmetals
I3: Cross the
numbers from
the charges
over and down.
Keep the
numbers
outside the
parentheses if
you have
polyatomic ions
I4: Reduce
if possible.
C2: The prefixes tell you
how many of each atom is
present
I5: Don’t write
ones or
parentheses if
there is only one of
an ion.
