The periodic table: an overview of chemistry
This area of study covers the relationship between major concepts of
chemistry investigated in this course and the previous course, e.g. and
and illustrated by a selection of chemicals within the framework of the
Historically, the periodic table developed as a system of classification
of elements based on the chemical and physical properties of the elements
themselves and their compounds. While the modern periodic table arranges
the elements into horizontal and verticalaccording to their atomic number,
 much of the development of the periodic table preceded the development
of modern atomic theory. Each step in the development of the periodic table
was effectively a summary of relationships between the elements and their
The term as in periodic table is taken for granted in chemistry. However,
many students falter when asked to explain why the term periodic is used.
Magazines that are published weekly or monthly are often called
periodicals, reflecting the fact that there is a defined period of time
between issues. In terms of the periodic table, a is a (number) that must
be covered Once this element is encountered, a new period begins. The
development of atomic theory was the key to logical explanations of
periodicity, but it did not lead to any significant changes in the
structure of the periodic table.
There are many versions of the periodic table available on the Internet.
