Metallic silver has fcc structure. If radius of Ag atom is 144 pm . What is the edge length of unit cell?

Options

  1. A4.07 10⁻⁸ ~cm
  2. B3.22 10⁻⁸ ~cm
  3. C2.63 10⁻⁸ ~cm
  4. D.2 .23 10⁻⁸ ~cm

Correct answer

A. 4.07 10⁻⁸ ~cm

Step-by-step solution

For fcc type of unit cell, r= 2 4 a =0.3535 a a= 144 pm 0.3535 =407 pm =4.07 10⁻⁸ ~cm
