Question

Lithium selenide can be described as a cubic closest-packed array of selenide ions with lithium ions in all of the tetrahedral holes. Formula of lithium selenide is

• A. $L{i}_{2}Se$
• B. $LiSe$
• C. $LiS{e}_2$
• D. $L{i}_{3}Se$

Answer 1

The correct option is A $L{i}_{2}Se$

Answer(A):- $L{i}_{2}Se$

If number of Se =Z , Number of Li = 2Z
