![]() Credited as being the creator of the first version of the periodic table of elements.His method allowed chemists to search for a relationship between atomic mass and other properties of elements.Determined a method for accurately measuring the relative masses of atoms.table are interrelated in terms of atomic number. I can describe how the elements belonging to a group of the periodic.I can explain how the periodic law can be used to predict the physical and chemical properties of elements.I can describe the modern periodic table.I can explain the roles of Mendeleev and Moseley in the development of the periodic table.Chapter 5 – Section 1history of the periodic table Today elements are ordered according to atomic number rather than atomic mass. Mendeleev arranged the elements in rows according to atomic weight and kept elements with similar chemical properties in the same columns. At the same time, it was recognized that there were certain elements that had similar chemical properties. The physical property called atomic mass provided chemists with a convenient way to organize the elements. Certain characteristic physical and chemical properties were associated with each element. In the late 1800s, scientists had identified over 60 elements.
