Collection of elements arranged after Mende
© Science Museum / Science & Society Picture Library
Collection of elements arranged after Mendeleyev's periodic clasification of about 1869, September 1926. Dmitry Mendeleyev (1834-1907), was a Rusian chemist who formulated the periodic table of elements, which grouped the elements according to their atomic structure and chemical properties. His work enabled chemists to identify 'families' of elements with similar chemical and physical properties and has influenced ideas in organic chemistry ever since. In 1955, a new element, atomic number 101, was named mendelevium (Md) in his honour. Almost all of the specimens were bequeathed to the Science Museum by Prince Louis Lucien Bonaparte.
