Three elements B, Si and Ge are

A

metals

B

non-metals

C

metalloids

D

metal, non-metal and metalloid respectively

Text Solution

Verified by Experts

The correct Answer is:
C
The element boron (B), silicon (Si) and germanium (Ge) are metalloids. In the periodic table, metals have been separated from non-metals by some elements called 'metalloids' which are placed diagonally in the periodic table. These metalloids are B, Si, Ge, As (arsenic), Sb (antimony), Te (tellurium) and (Po) polonium.
