History of the Periodic Table

The elements are listed in a chart called the periodic table. They are in order of their the number of protons.

There are 118 elements on the periodic table.

The first scientist to create an organization of elements was Johan Dobereiner. In 1829, He organized three groups called triads, but this system didn't work. Later, a scientist named John Newlands, organized another chart which had 8 groups in it. He called it the Law of Octaves. Unfortunately, this chart didn't work either. Finally, in 1869, a German scientist named Dmitrii Mendeleev created the periodic table we use today!
