$A$ metal $(M)$ crystallizes in $bcc$ lattice. The number of atoms of $M$ per unit cell is $2$.

Vedclass · Answer

(A, B) In a unit cell,the edge lengths are $a$,$b$,and $c$. The angle between $b$ and $c$ is $\alpha$,between $a$ and $c$ is $\beta$,and between $a$ and $b$ is $\gamma$. Thus,option $A$ is correct.In a $bcc$ (body-centered cubic) lattice,the number of atoms per unit cell is $1$ (at center) $+ 8 	imes (1/8)$ (at corners) $= 2$. Thus,option $B$ is also correct.$SiC$ (Silicon carbide) is a covalent network solid,not an ionic solid. Thus,option $C$ is incorrect.For a triclinic lattice,the relationship is $\alpha 
eq \beta 
eq \gamma 
eq 90^{\circ}$. Thus,option $D$ is incorrect.Note: Both $A$ and $B$ are factually correct statements.
