If the positions of Na^(+) and Cl^(-) are interchanged in NaCl, having fcc arrangement of Cl^(-) ions then in the unit cell of NaCl

Assertion. The sum of the radii of Na^(+) and Cl^(-) ions in NaCl cystal is 281 pm Hence, edge of the unit cell is 281 pm. Reason. Edge of the unit cell is the distance between the centres of Na^(+) and Cl^(-) ions touching each other.
