If a is the edge length of unit cell of sodium chloride, the distance between the two nearest Na^(+) ions is

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.
