on atomic weight. An Element is a type of atom that is defined by its atomic number (number of protons or electrons atomic mass, symbol, and much more but for now lets start with the basics. Critics leaped on these omissions, claiming they proved that the concept was seriously flawed. Development of the Periodic Table Essay.development OF THE, periodic table Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form. A number of scientists tried different kinds of patterns. I think without the development of the periodic table we may not have different types of medicines, or maybe just generic products to help us along the way of life. Society has really take advantage of the quality and put forth a great effort to answer questions for life before chemistry. The idea of putting the elements together finally took shape when the two scientists, Dmitry Mendeleev and Julius Lothar Meyer successfully arranged the order of the elements by their atomic weight and discovered that the properties of the elements recur in the same pattern. His periodic law states that the chemical and physical properties of the elements vary in a periodic way with their atomic weights.

The Periodic, law, the modern periodic table, based on atomic number and electron configuration, was created primarily by a Russian chemist, Dmitri Ivanovich Mendeleev. Mendeleev created the first periodic tablebased on atomic weight.

The pattern had to do with the valence, or combining power, of the elements. When he arranged the elements according to their atomic weight, he found a pattern not discovered by his predecessors. This experiment was the discovery of phosphorus. Research Papers 856 words (2.4 pages). Into the 1930s the heaviest elements were being put up in the body of the periodic table, and Glenn Seaborg took those out while working with Fermi in Chicago, naming them the Actinide series, which later allowed the proper placement of later created elements like. Hennig Brand tried to make a Philosophers stone, which was an object that could possibly turn metal into gold. tags: essays research papers.
