Question

if the diagonal of bcc unit cell be 8√3.find the radius of the atom.​

Answer 1

Answer:

Here is your answer

Explanation:

In FCC: The atoms at the face diagonals touch each. If a is the edge length of cube and r is the radius of the atom.

So,

2

a=4r

⇒a=2

2

r

In bcc: The atoms at the body diagonal touch each other.

So,

3

a=4r

⇒a=

3

4

r

In simple cubic: The atoms at the corners touch each other.

So, a=2r
