Question

An element crystallized is in FCC what is the length of side of unit cell if atomic radius of element is 0.144nm

Answer 1

Answer:

Explanation:

For fcc unit cell, a=2root2r

Here, a is the edge length and r is the atomic radius (0.144 nm).

a=2 root2 ×0.144=0.407 nm

Hence, the length of a side of a cell is 0.407 nm.
