Question

Statement: ${\text{Na}}_2\text{O}$ has anti-fluorite structure.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is A True

${\text{Na}}_2\text{O}$ has anti-fluorite structure.
${\text{O}}^{2-}$ ions form fcc unit cell. ${\text{Na}}^{+}$ ions occupy tetrahedral voids.

${\text{Na}}_2\text{O}$ has 4:8 coordination.

Hence, the given statement is $\text{true}$.
