A chemical formula provides information about the elements that make up a compound and the ratio in which the atoms of those elements combine to form molecules. The preferred way to name a chemical is using IUPAC nomenclature, which assigns each chemical a unique systematic name according to IUPAC guidelines. Common names are also used and are unambiguous but do not follow current IUPAC naming conventions. Examples of common chemical formulas and their uses are provided.

1. CHEMICAL FORMULA
a symbolic representation
of its chemical composition.

2. CHEMICAL FORMULA
Chemical formulas provide
understanding into the elements
that constitute the molecules of a
compound and also the ratio in
which the atoms of these
elements combine to form such
molecules.

3. EXAMPLE
𝐻2𝑂
There is 2 atoms of Hyrogen and 1 atom of xygen

4. WAYS OF NAMING CHEMICALS
𝑰𝑼𝑷𝑨𝑪 𝑵𝑨𝑴𝑰𝑵𝑮
preferred way to name a
chemical because each
systematic name
identifies exactly one
chemical

5. WAYS OF NAMING CHEMICALS
𝑰𝑼𝑷𝑨𝑪 𝑵𝑨𝑴𝑰𝑵𝑮
The systematic name is
determined by guidelines set
forth by the International Union
of Pure and Applied Chemistry
(IUPAC).

6. WAYS OF NAMING CHEMICALS
𝑪𝑶𝑴𝑴𝑶𝑵 𝑵𝑨𝑴𝑰𝑵𝑮
defined by the IUPAC as a name
that unambiguously defines a
chemical, yet does not follow
the current systematic naming
convention.
