Question

What was the name given to Eka-silicon after it was discovered?

Answer 1

Mendeleev's periodic table:

• Mendeleev arranged the elements in vertical columns and horizontal rows in the increasing order of their atomic weights.
• He left a gap for the undiscovered elements below Aluminium and Silicon and called them Eka-aluminium and Eka-silicon.

Eka-silicon:

• Eka-silicon was the name given to the element below silicon in Mendeleev's Periodic table which was not discovered at that time.
• When this element was discovered, it was given the name Germanium (Ge).
