Which eka silicon element was predicted by Mendeleev?
Eka Silicon
The three elements predicted by Mendeleev from the gaps in his periodic table were known as eka-boron, eka-aluminium and eka-silicon. What names were given to these elements when they were discovered later on?
The correct formula of the oxide of Eka-aluminium element predicted by Mendeleev was :
(a) EaO3 (b) Ea3O2 (c) Ea2O3 (d) EaO
Mendeleev predicted the element eka-silicon, meaning 'beyond silicon', which was later found to be Phosphorous.
