D

Gold

Text Solution

Verified by Experts

The correct Answer is:
A
Polonium is a radiactive element having two metallic allotropic forms , `alpha-" form "andbeta-` form. Out of these two forms, `alpha` - Po form crystallises as simple cubic crystal. Copper and gold crystallises in face centred cubic crystal and iron crystallises in body centred cubic crystal and iron crystallises in body centred cubic crystal .
