The First Periodic Table The first periodic table was published in 1872 by man named Dmitri Mendeleev.

Rows and Columns The Periodic Table consists of 7 rows also known as shells. These sets are horizontal on the table. The vertical set of elements are known as Columns or groups. There are 18 of these on the table.

Elements on the table The elements are arranged in increasing order of Atomic Number, which is read from left to right. The elements are grouped into separate categories on the table.

Elements of the table cont. Groups 1 & 2 on the table are known as the light metals or alkali metals. Groups 3-12 on the table are known as the transition metals, this group is indented on the table

Elements on the table cont. Groups are known as the non- metals, with group 17 being the halogens. Group18 consists of the noble gases.

Elements on the table cont. Elements on the table are known as the lanthanide series or rare earth metals. Elements on the table are known as the actinide series. Elements can be found at the bottom of the periodic table.
