Question

Percentage fraction of edge length not covered by atom when metal crystalises in bcc

Answer 1

$\huge{\mid{\boxed{\sf{\color{purple}{AnS}{\color{pink}{WeR}}}}}\mid}$

$in \: bcc \: lattice \:$

$4r \: = \sqrt[a]{3}$

$fraction \: of \: each \: edge \: covered \: by \: atoms \: is$

$\frac{2r}{a} = \frac{ \sqrt[a]{3} }{2a} = 86.6\%$

therefore fraction of edge not covered by atom is 13.4%

Answer 2

Answer:

Therefore the fraction of edge not covered by atom is 13. 4%
