For scientists who work with many different elements, the periodic table is so indispensable it can easily be forgotten that this is not divine intuition but the result of extremely hard work.
The inspired genius of scientists like Mendeleyev and Julius Meyer (1830-1895) gave chemists the advantages of the periodic table about a half century before the existence of the electron was proved. Mendeleyev's confidence in his table and his logically derived predictions are the basis of extended form of it presented here. Its later expansion and predictions by Glenn T. Seaborg (1912-1999) strongly influenced science and especially physics, and thereby made the creation of new elements possible for the first time. With each newly discovered element and with the advance of research and technology, the picture of the periodic table has grown into an important construct underlying all areas of science as well as the mathematics and informatics. Thus, though the periodic table itself is subject to unexpected changes ( ANTIMATTER ), its importance makes the attempt of further prediction worthwhile.
