Answer to Question #178175 in Atomic and Nuclear Physics for lethukuthula sikhakhane

Question

what is the atomic spacing between two iron atoms?

Answer 1

To be given in question

Atom= iron atom

To be asked in question

Atomic space in iron atom

We know that

Room temperature iron atom is bcc type structure

BCC type structure

Use pithagorse theorem

$(bd)^2=a^2+(fd)^2$

$(bd)^2=a^2+(2a^2)$

$(4r)^2=3a^2$

$a=\frac{4r}{√3}$

Inter spacing between iron atom

$2r=\frac{a√3}{2}$
