WebThe periodic table By convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior. Devised by Russian chemist … In 1817, German physicist Johann Wolfgang Döbereiner began to formulate one of the earliest attempts to classify the elements. In 1829, he found that he could form some of the elements into groups of three, with the members of each group having related properties. He termed these groups triads. Chlorine, bromine, and iodine formed a triad; as did calcium, strontium, and barium; lithi…
