A given metal crystallises out with a cubic structure having edge length of 361 pm. If there are four metal atoms in one unit cell, What is the radius of one atom? (AIPMT 2015)

Given, edge length = 361 pm Four metal atoms in one unit cell i.e., effective number in unit cell (Z) = 4 (given) SOLID STATE 31 It is a FCC structure, Face diagonal = 4r 2a 4r 2 361 r 127pm 4 x >>
