Number of Na^(+) and Cl^(-) ions associated with each a unit cell of NaCl is:

r_(Na^(+))" and " r_(Cl^(-)) represent radius of Na^(+) and Cl^(-) ions respectively. If 'n' is the number of NaCl units per cell then give the eqution you will use to obtain molar volume.

The radius of Na^(+) is 95pm and that of Cl^(-) is 181 pm. The edge length of unit cell in NaCl would be (pm).

How many effiective Na^(+) and Cl^(-) ions are present respectively in a uint cell of NaCl solid (Rock salt structure ) if all ions along line connecting opposite face centres are absent ?

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.
