The periodic law states that the physical and chemical properties at the elements are periodic functions at their atomic numbers. The periodic table or the elements is one of the most imponant tools ot a scientist, especially a chemist. In 1863, there were 56 known elements with a new element being discovered at a rate of approximately one per year. Other scientists had previously identified periodicity of elements. John Newlands described a Law of Octaves, noting their periodicity according to relative atomic weight in 1864, publishing it in 1865. His proposal identified the potential for new elements such as germanium. The co… high beach club
