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.
Dmitri Ivanovich Mendeleev (/ ˌ m ɛ n d əl ˈ eɪ ə f / MEN-dəl-AY-əf; [2] [b] [a] 8 February [O.S. 27 January] 1834 – 2 February [O.S. 20 January] 1907) was a Russian chemist known for formulating the periodic law and creating a version of the periodic table of elements.
However, success of Mendeleev's predictions helped spread the word about his periodic table. [56] Later, chemists used the successes of these Mendeleev's predictions to justify his table. [15] By 1890, Mendeleev's periodic table had been universally recognized as a piece of basic chemical knowledge. [57]
Consequently, Mendeleev organized the elements known at that time into a table with eight columns. He used the table to predict the properties of then unknown elements. While his hit rate was less than 50% it was his successes that propelled the widespread acceptance of the idea of a periodic table of the chemical elements. [8]

In 1869, Dmitri Mendeleev predicted its existence and some of its properties from its position on his periodic table, and called the element ekasilicon. On February 6, 1886, Clemens Winkler at Freiberg University found the new element, along with silver and sulfur , in the mineral argyrodite .
