The Periodic Table of Elements
In September 1860 the birth of the Periodic table began. A group of the world’s best chemists assembled in Germany to discuses the issues of atomic mass. At this meeting an Italian chemist, Stanislao Cannizzaro, introduced the right way to accurately measure the relative mass of an atom. After the new method was introduced chemists started to recognize similarities in the properties of various elements and placed them into families. In this earlier stages of the periodic table there were four main chemists; Dobereiner, Newlands, Lothar Meyer, and Dmitri Mendeleev that played a substantial role in the development of the periodic table. Dobereiner started with a few family groups each containing three elements. Newlands put the elements of those families in repeating groups called octaves. Meyer noted additional repeating properties. Mendeleev put it all together into what has become the periodic table of the elemen...
