The Periodic Table
The Periodic Table of the Elements contains all the elements known to man. The periodic table is organized according to certain characteristics of the elements.
Answer and Explanation:
In the periodic table, rows of elements are defined as being periods, and groups are defined as being columns. For example, group 1A of the table contains all the group 1 elements, and is the first column that appears in the table on the left side.
The table is organized in such a way that elements with similar properties appear in the same group, and it's also organized with the elements increasing in atomic number across a period.
