Question

The predicted name for germanium is

• A. eka-boron
• B. eka-silicon
• C. eka-aluminium
• D. eka-scandium

Answer 1

The correct option is B eka-silicon

Mendeléev predicted the existence of some elements that had not been discovered at his time and named them by prefixing a sanskrit numeral, eka (one) to the name of the preceding element in the same group. Therefore, germanium, discovered later, has properties similar to eka–silicon predicted by him.
Hence, the correct answer is option (b).
