The Periodic Table Of Elements

The periodic table is a tablet of elements created to organize science and functions. Each one has a atomic number and there name. This tablet was used to organize all the elements in our world and the data needed to learn of all the elements. The most known element is hydrogen

History:

In 1789, Antoine Lavoisier published a list of 33 chemical elements. Although Lavoisier grouped the elements into gases, metals, nonmetals, and earths, chemists spent the following century searching for a more precise classification scheme. In 1829, Johanna Wolfgang observed that many of the elements could be grouped into triads based on their chemical properties.
