      The periodic table is an arrangement of elements based on atomic number. The modern Periodic Table was developed in 1913 by Henry Moseley. He used X-rays to identify the atomic number of each element. When elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern.

      For example, some sources list the atomic weight of seaborgium as 263 and others 266. The most stable isotope appears have an atomic weight of 266 so we list that weight here. Roentgenium is still the unofficial name of element 111 but it is the one recommended by the IUPAC so we list it here instead of the generic ‘unununium’.
