In the given crystal structure what should be the cation X which replaces Na+Na^{+}to create a cations vacancy?

A

Sr2+Sr^{2 +}

B

K+K^{+}

C

Li+Li^{+}

D

Br−Br^{-}

Answer

Sr2+Sr^{2 +}

Explanation

Solution

Each Sr2+Sr^{2 +}in the NaCl crystal replaces tow Na+Na^{+}ions. It occupies the site of one ion and the other remains vacant creating a cation vacancy.
