Transition Metal Naming

Transition Metal Naming
The transition metals are located in Groups 3 to 12 on the periodic table, and the elements Indium (In), Tin (Sn), Lead
(Pb) and Bismuth (Bi).
The reason transition metals are named differently than the main group elements is that they have "d" orbitals and
as a result, they can have MORE THAN ONE oxidation states. It is very important that the oxidation state is noted
because IONS WITH DIFFERENT OXIDATION STATES REACT IN DIFFERENT WAYS.
For example, sodium has only one oxidation state: +1.
But, Copper, a transition metal has two oxidation states: +1 AND +2. Both ions react in different ways.
Iron has two oxidation states: +2 and +3. The human body can only use the Fe+2 ion to make hemoglobin which
carries oxygen around the body in red blood cells. Fe+3 is not taken up by the body be cause is reacts in a totally
different way than Fe+2.
NOTE: ZINC AND SILVER HAVE ONLY ONE OXIDATION STATE: Zn+2 and Ag+1.
To remember this, remember the following:

HOW TO DETERMINE THE OXIDATION STATE OF A TRANSITION METAL IN A COMPOUND
BINARY COMPOUNDS WITH TRANSITION METALS: The goal is to balance out the oxidation states so that they
equation zero when added.
1. Determine the oxidation state of the non-metal (anion) in the compound. For example, in FeCl2, chlorine has an a
+1 oxidation state.
-1
Cl
2. If there is more than one anion present, multiply its charge by the subscript.
Cl2
-1 = -2
3. The two chlorine atoms have a total charge of -2. In order to balance out the charges so the compound has an
over charge of ZERO, the iron ion must have a charge of +2.
+2
Fe
+
-2 = 0 (zero)
Cl2-1
So the correct charge on the iron ion is +2. We name this compound Iron(II)chloride. The (II) is a Roman numeral
used to indicate the charge on the iron atom. We use the "-ide" ending on the chloride because it is a binary
compound.

Example: What is the correct name of CrCl3 ?
The charge of Cr is unknown = x . But chloride = (-1). The sum of the charges has to be
zero, so:
Answer:
x + 3(-1) = 0.
x = 3.
CrCl3 = chromium (III) chloride.

TERNARY COMPOUNDS WITH TRANSITION METALS (those which contain a polyatomic ion).
Recall that polyatomic ions are a group THAT STAYS TOGETHER and has ONE CHARGE. (There are exceptions, but
they are not part of this course.)
The same procedure is used. Example: What is the name of the compound Cd(NO3)4.
We know that the NO3 polyatomic ion has a charge of -1. But there are four nitrate groups present, each with a
change of -1, so the total charge on the nitrate group is -4. Since there is only one Cd present, the charge on it must
be -4, so that the charge on the whole compound equals zero.
+4
+
-4
=
0 (zero)
Cd (NO3)4 -1
So the name of this compound is Cadmium(IV)nitrate. Use the name of the polyatomic as listed on Table E.
---------------------------------------------------------------------------------------------------------------------------------------------------------If there is more than one metal present, determine its charge by dividing the total negative charge by the number of
metal ions present.
Example: Sn3P2
We know that phosphorous has an ionic charge (oxidation state) of -3. BUT, there are two phosphorous ions present,
so the total charge for phosphorous is -6.
P2-3 = -6
There are THREE tin ions present and the total charge on the tin must be +6. If we divide 3 into 6, which will give us
2. This means there is a charge on the iron is +2.
Sn3+2 = +6
+6
The total charge on the compound is zero:
Sn3+2
+
-6
= 0
P2-3
The name of this compound is Tin(II) Phosphide. The (II) indicates the charge on the tin. It is the same for
compounds with polyatomic ions.
