Chromium metal crystallizes with a body-...

Chromium metal crystallizes with a body-centred cubic lattice. The length of the unit cell edge is found to be `287`pm. Calculate the atomic radius. What woulds be the density of chromium in `g cm^(-3)`?

Text Solution

Verified by Experts

In body-centred cubic unit cell, `asqrt(3)=4r`
where , a=edge length, r=radius of atom
`r=(asqrt(3))/(4)=(sqrt(3)xx4.29)/(4)=1.8574 Ã…`
