Chemical Elements Table with 7 Periods, 7 Rows, and 18 Groups

The table of chemical elements that consists of 7 periods, 7 rows, and 18 groups is known as the long form periodic table. This table is an extended version of the traditional periodic table and provides a more comprehensive view of the relationships between the elements.

The long form periodic table was developed by Glen T. Seaborg and his colleagues in the 1940s. It is also known as the extended periodic table and includes the actinides and lanthanides in addition to the elements found in the traditional periodic table.

The 7 periods in the long form periodic table represent the energy levels of the elements, while the 7 rows correspond to the periods, and the 18 groups represent the columns in the table.

The long form periodic table is a valuable tool for understanding the properties and relationships of chemical elements, and it provides a more comprehensive framework for studying the behavior of elements based on their atomic structure and properties.
