Dmitry Ivanovich Mendeleyev (sometimes spelled 'Mendeleev') is one of the greatest Russian chemists to have ever lived. One of his many accomplishments was devising a way to organize the known elements by showing that they exhibit a periodicity, or regular pattern, of properties when they are arranged according to their atomic weights. This meant that he could predict the properties of the next elements before they were discovered. Other investigations of his include the study …showed first 75 words of 1135 total…

He rose from being the fourteenth child from a poor family in an obscure region to a scientific hero who pioneered many areas of the field of chemistry. He organized all the elements into one convenient, universally used table, almost won the Nobel Prize, and even has his own element named after him. Few chemists have matched Mendeleyev's success and contributions to the study of science before or since.
