WebAnswer (1 of 2): eka- in Chemistry is a prefix used to designate the first element of the same family in the periodic table beyond the one to whose name it is prefixed, as ekaselenium for technetium. All the eka-ele-ments were later discovered: eka-aluminum (1875) was called gallium; eka-boron (... WebHe constructed the names by adding the prefix eka, which is Sanskrit for the number 'one'. So, Mendeleev said, we should have eka-boron, eka-aluminium, eka-manganese and eka-silicon. ... Eka-silicon, for instance, is now called germanium and measured up well to Mendeleev's predictions. Similarly, for a long time it was assumed that element 114 ...

WebMar 23, 2024 · This gap corresponds to the element which lies in a periodic table. He named these undiscovered elements as Eka silicon and Eka aluminium. Later on, in the modern periodic table, the eka silicon is germanium .it has similar properties as that of silicon. Eka aluminium is gallium. It has similar properties as that of aluminium. To give provisional names to his predicted elements, Mendeleev used the prefixes eka- /ˈiːkə-/, dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 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. For example, germanium was called eka-silicon until its discovery in 1886, and rhenium was called dvi-manganese before its discovery in 1926. ckd 3 and protein
