Periodic Table
What is the periodic table? The periodic table is a rectangle that every one to day recognizes. This function of grouping the chemical elements was created by several European scientists; it all started in the 1860’s. In 1863, a French geologist, A. E. Béguyer de Chancourtois created a list of the elements in the periodic table and arranged the elements by increasing atomic weight. The list was wrapped around a cylinder so that sets of similar elements lined up, creating the first representation of the periodic table. In England, a chemist by the name of John A. R. Newlands was also wrapping the elements, noticing that the chemical groups repeated after every eight elements. He named this the octave rule, and compared it to a musical scale. His work was considered to be absurd, so his work was ignored for years. Chemists Dmitrii I. Mendeleev, a Russian, and German Lothar Meyer were working independently to arrange the elements into seven columns, corresponding to various chemical and physical properties. Then latter came the periodic table as of to day to be what we see. Some of the parts of the modern periodic table are groups/families, and periods.There are many groups/families in the periodic table. The Alk
