What will be the percent fraction of edge length not covered by atoms when a metal crystallises in bcc lattice?

A

`11.4%`

B

`10.4%`

C

`13.4%`

D

`12.4%`

Text Solution

Verified by Experts

The correct Answer is:
C
`"Fraction"=(a-2R)/(a),R=(sqrt3a)/(4)`
`=(a(1-(2sqrt3)/(4)))/(a)=1-(sqrt3)/(2)=0.134`
`%=13.4`
