An element with simple cubic close structure has edge length of unit cell 3.86 Å . What is the radius of atom?
Options
- A5.79 10⁻⁸ ~cm
- B1.93 10⁻⁸ ~cm
- C3.86 10⁻⁸ ~cm
- D2.43 10⁻⁸ ~cm
Correct answer
B. 1.93 10⁻⁸ ~cm
Step-by-step solution
In simple cubic close structure aligned & a =2 r & r = a 2 = 3.86 2 =1.93 Å & r =1.93 10⁻⁸ ~cm & (1 ~A ^ =10⁻¹⁰ ~m =10⁻⁸ ~cm ) aligned
