Prefixes Used to
Indicate Number in a Name Involving Two Non-Metals
mono– 1 hexa– 6
di– 2
hepta– 7
tri– 3
octa– 8
tetra– 4
nona– 9
penta– 5 deca–
10
·
These prefixes are
used in naming binary compounds involving two non–metals. Example include P2O5, Cl2O, NO, N2O,
NO2, N2O5, PCl3, PCl5, SO2, SO3, SiO2.
·
Sometimes metal
ions are involved in a Greek prefix name, but these are less common. Examples
include UF6, SbCl3,
SbCl5, OsO4, BiCl3.
·
CO is carbon
monoxide, NOT carbon monooxide. As4O6 is tetrarsenic
hexoxide, NOTtetraarsenic hexaoxide.
·
Acid Names – add
the word acid to each name when saying or writing.
·
Name when a pure compound Name when dissolved in water
HF hydrofluoric
acid hydrogen fluoride HNO3 nitric acid
HCl hydrochloric acid hydrogen chloride HNO2 nitrous acid
HBr hydrobromic acid hydrogen bromide
H2SO4 sulfuric acid
HI hydroiodic acid hydrogen iodide H2SO3 sulfurous acid
HCN hydrocyanic acid hydrogen cyanide H3PO4 phosphoric acid
H2S hydrosulfuic
acid hydrogen sulphide H2CO3 carbonic acid
Acetic acid CH3COOH)
What are the Latin Names of
Elements?
Scientists have adopted certain conventions regarding the
chemical symbols for various elements. The symbol is the short form or
abbreviated name of the element. Each element has a chemical symbol that is
unique to it. An atom of an element is denoted by this symbol. For example, the
symbol for Carbon is C.
Many elements have their symbol derived from either the
first letter [e.g., H for Hydrogen] or the first two letters [e.g., He for
Helium] of their names. A few elements have symbols derived from their Latin
names as given in the table below.

Ionic Compound Formula Writing Worksheet
QUESTION-1
Write chemical formulas for the
compounds in each box. The names are
found by finding the intersection between the cations and anions. Example:
The first box is the intersection between the “zinc” cation and the
“chloride” anion, so you should write “ZnCl2”, as shown.
