    To give provisional names to his predicted elements, Dmitri Mendeleev used the prefixes eka- / ˈ iː k ə-/, [note 1] dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, [3] depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table.

    Mendeleev's periodic table had brought order to all the elements, allowing him to make predictions that future scientists tested and found to be true. By the time he died he was world-renowned in chemistry. His periodic table was set in stone in St Petersburg and an element was eventually named after him: mendelevium.

    Mendeleev organized the elements based on atomic weight, leaving empty spaces where he believed undiscovered elements would take their places. [3] Mendeleev's discovery of this trend allowed him to predict the existence and properties of three unknown elements, which were later discovered by other chemists and named gallium , scandium , and ...

    1906 — Mendeleev's table: with six supposedly missing elements between H and He [15] 1919 — Hackh's table, with 9 columns in the top half and 11 in the bottom half. The position of an element in the table determines its properties. [16] [n 4] 1923 — Deming's other table: Mendeleev style with dividing line between metals and nonmetals [17]
