If the lattice parameter for a crystalline structure is

3.6 \%

, then the atomic radius in fcc crystal is $If the lattice parameter for a crystalline structure is 3.6 \% , then the atomic radius in fcc crystal is$ $If the lattice parameter for a crystalline structure is 3.6 \% , then the atomic radius in fcc crystal is$

Options

A $1.27 \&$
B $1.81 Å$
C $2.10 Å$
D $2.92 \&$

Correct answer

A. $1.27 \&$

Step-by-step solution

$If the lattice parameter for a crystalline structure is 3.6 \% , then the atomic radius in fcc crystal is$
2 R=

\frac{a}{\sqrt{2}} \therefore

R=

\frac{a}{2 \sqrt{2}}
