Chemical Nomenclature Unit
Valence Value
The valence value of an element is defined as the number of electrons an atom of that element will
gain/lose/share when forming a compound. Elements have a valence value determined by their group on
the Periodic table unless otherwise indicated by the name.

Cross-Over Rule for Writing Formulas
STEPS
1. Write down the symbols of
the elements in the order given
in the name.
2. Write the valences above the
elements symbol.
3. Divide the valences by the
highest common multiple.
4. Cross-over valences
5. Drop all 1’s and unnecessary
brackets

Notes:
a) You should be able to do all 5 steps in your head when you are finished the unit.
b) When naming compounds, the least electronegative element is usually written first.
c) Groups of elements such as SO42- and CO32- are referred to as radicals or polyatomic ions. These radicals
behave as if they were a single entity and follow the cross over rule in the same manner as other single
elements. Brackets are used in the formula only if there are 2 or more of the radical indicated in the
formula. For example, brackets are used in Al2(SO4)3 but not Na2SO4.
Binary Ionic Compounds
A binary compound contains 2 elements only.
Rules for Binary Ionic Compounds:
a) The name of the binary compound always ends in "ide".
b) The first mentioned element may have more than one valence and if it does this must be indicated in
the name.
c) If the valence of the first element is not indicated in the name, their valence value is determined by their
group on the Periodic table.
A) Binary Compounds where the first element has 1 valence only
Use rule “c” and the cross-over rule. Silver has a valence of 1, zinc and cadmium have a valence of 2.

B) Binary Compounds with Multivalent Elements
Many transition metals and some other elements have multiple valence values and therefore can form multiple
compounds with the same non-metal. Due to this it is necessary to indicate the valence of the metal in the name of the
compound using either the Stock (IUPAC or Roman Numeral) or Classical (“ous” and “ic”) method. The second element
(non-metal) always has a valence equal to the value as determined from its group in the periodic table. The table of
multivalent elements that you have been given must be MEMORIZED!
Method 1: Stock/IUPAC/Roman Numeral Method
This is the currently preferred method as the valence of the first is indicated using the corresponding Roman Numeral in
brackets following the name of the first element.

Method 2: Classical/"ous' and "ic" Method
This method can be used when the multivalent element has 2 possible valences. The name of the element ending with
"ous" denotes the lower valence value and the name of the element ending with an "ic" denotes the higher valence
values. In some cases, the Latin name for the element is used.

Common Radicals or Polyatomic Ions
Radicals or polyatomic ions are groups of atoms that are treated as a single entity when writing formulas and names.
The following list of common radicals (polyatomic ions) must be memorized along with their valences. Positive
polyatomic ions replace metals in an ionic compound and a negatively charged polyatomic ion goes in place of the nonmetal. If more than 1 of the radical is required in the chemical formula, brackets are placed around the radical’s formula
with the subscript outside the bracket.

Acids
There are three groups of acids:
1. binary acids
1. Binary Acids
This is a very small but common group of acids. The following rules apply to all of the members.
1. All have the prefix “hydro” and end with “ic”.
2. All must contain hydrogen as the first element.
3. Use the normal cross-over-rule to determine the formula.
4. All are made by dissolving the gas in water and must be so indicated by using (aq) behind the formula.
5. Have no oxygen in their formula
Examples:
hydrochloric acid
HCl(aq)
hydrosulfuric acid
H2S(aq)
hydrocyanic acid
HCN(aq)

2. Oxy Acids
This is a larger group of acids. They are alike in that they all contain H, O and at least one other non-metal element. All
members of this group of acids follow the rules below.
1.
2.
3.
4.
The name of the acid ends in “ic”.
The name of the associated radical ends in “ate”.
The valence value of the associated radical is equal to the number of acidic hydrogens in the acid.
Since these acids are made by reacting a non-metal oxide with water, (aq) is not required but may be used.
The following 6 oxy acids and their associated radicals along with their valences must be memorized.

NOTE:
Using the periodic table it is possible to write the names and formulas for a number of other oxy acids using the fact that
members of the same chemical family have similar chemical properties. Elements of the same chemical family (group)
follow the pattern of the memorized oxy acid immediately above the element of interest.
Example:
memorized acid: fluoric acid = HFO3
therefore: chloric acid = HClO3
iodic acid = HIO3
bromic acid = HBrO3
If hydrogen is joined with the radicals learned earlier a few more acids can be formed.
chromate = CrO42-
chromic acid = H2CrO4
cyanate = CNO-
cyanic acid = HCNO

Theses acids are all derived from the parent oxy acids which you are to memorize. The table below shows the rule to
determine the derived oxy acids from the parent acid. When adding or removing oxygen atoms from the parent acid,
the number of hydrogens on the acid and the valence of the associated radical remain the same as the parent.

Salts
The word, salt, is the general term given to a class of compounds which can be formed when an acid and a base
neutralize each other. According to this definition then, most of the compounds dealt with in the section on binary
compounds could be considered to be salts formed from a base and a binary acid. In the same manner, salts are formed
from a base and an oxy acid or derived oxy acid.

sodium sulphate
aluminum carbonate
cupric nitrite

Acid Radicals and Acid Salts
1. Acid Radicals
In certain circumstances the oxy acids with multiple acidic hydrogens are able to lose the hydrogens one at a time. This
results in radicals with acidic hydrogens still attached which are referred to as acid radicals.
Step 1: H3PO4 (aq) H+ (aq)+ H2PO4-(aq)
Step 2: H2PO4-(aq)  H+ (aq)+ HPO42-(aq)
Step 3: HPO42- (aq) H+(aq) + PO43-(aq)
Radical
Name
Valence
PO43-(aq)
Phosphate
3
HPO42-(aq)
monohydrogenphosphate
2
H2PO4 (aq)
dihydrogenphosphate
1
Notes:
a) valence = # of hydrogen removed from the acid OR valence of non-acid radical-# of H’s still attached
b) mono may be left off a monohydrogen acid radical
c) for oxy acids with 2 acidic hydrogens (diprotic acids), the prefix “bi” may be used in place of monohydrogen
(eg. HCO3- can be named as bicarbonate or monohydrogen carbonate)

For the following give the formula and valence value of the radicals listed: All radicals are aqueous

Hydrates
Hydrates are crystals containing a given number of water molecules within their structure. When naming a hydrate
Greek prefixes in front of the word hydrate are used to indicate the number of water molecules into the crystal. In the
chemical formula the number of water molecules is separated from the formula of the compound by a dot “∙”
Examples:
copper(II) sulfate pentahydrate

Molecular Compounds
These compounds contain 2 non-metals and are named using Greek prefixes. This method does not use the valence
values. The Greek prefix is placed in front of the element name to indicate how many atoms of the element to place in
the formula. If there is only 1 atom of the first element, mono is not used on the name of the first element.
Prefixes
1 = mono
2 = di
3 = tri
4 = tetra
5 = penta
6 = hexa
7 = hepta
8 = octa
9 = nona
10 = deca
