Polonium crystallises in a simple cubic ...

Polonium crystallises in a simple cubic structure. If the edge length of the unit cel is 336 pm, calculate the atomic radius of polonium.

Text Solution

Verified by Experts

The correct Answer is:
168 pm
Edge length (a) = 336 pm. For a simple cubic unit cell,
Atomic radius (r) `=(a)/(2)=(336)/(2)=168 "pm."`
