how did the work of dmitri mendeleev differ from that of john newlands in the development of the periodic table? mendeleev arranged the elements according to increasing atomic mass. mendeleev predicted elements that would later be discovered. mendeleev identified elements that had similar properties. mendeleev organized elements into triads based on their properties.

how did the work of dmitri mendeleev differ from that of john newlands in the development of the periodic table? mendeleev arranged the elements according to increasing atomic mass. mendeleev predicted elements that would later be discovered. mendeleev identified elements that had similar properties. mendeleev organized elements into triads based on their properties.

Answer

Brief Explanations:

Mendeleev left gaps in his periodic - table for elements yet to be discovered, which was a significant difference from Newlands. Newlands did not predict new elements in such a way. Arranging by atomic mass was done by both to some extent, identifying similar - property elements was also a common aspect among early periodic - table developers, and organizing into triads was more associated with Dobereiner.

Answer:

Mendeleev predicted elements that would later be discovered.
