The radius of chromium atom is `1.25Å`. If it crystallises in body centred cubic lattice, calculate the length of the edge of the unit cell.

Text Solution

Verified by Experts

The correct Answer is:
`2.89Å`
Radius (r) of chromium atom = `1.25Å.` For a body cented cubic lattice
Edge length `(a)=(4)/(sqrt3)r-(4xx1.25Å)/(1.732)=2.89Å.`
