What is the edge length of the unit cell of $NaCl$ crystal, when it is given that the distance between ${N a}^{+}$ and $C l^{-}$ ions in $N a C l$ crystal is $265 p m$ ?

Options:

Answer:

Solution:

For rock salt type structure,
$\frac{a}{2} = r^{+} + r^{-}$
$a = 2 (r^{+} + r^{-})$
$a {= 2 × distance between Na}^{+} and {Cl}^{-}$
$a = 2 × 265 = 530 pm$
