A cubic unit cell contains manganese ions at the corners and fluoride ions at the center of each edge. The radius of Mn ion is $0.65\stackrel{°}{\mathrm{A}}$ and that of ${\mathrm{F}}^{-}$ion is $1.36\stackrel{°}{\mathrm{A}}$

KF Crystalizes in the $\mathrm{NaCl}$ type structure. If the radius of ${\mathrm{K}}^{+}$ion is $132\mathrm{pm}$ and that of ${\mathrm{F}}^{-}$ion is $135\mathrm{pm}$. Choose the correct options

In a solid $\mathrm{AB}$ having $\mathrm{NaCl}$ type structure A atoms occupy the corner of the cubic unit cell and the face, centered positions. If all the face-centered atom along one of the axis are removed, choose the correct options:

(Atomic weight of $\mathrm{A}=40$),

Atomic weight of $\mathrm{B}=60, {\mathrm{r}}_{\mathrm{A}}=1.4\stackrel{°}{\mathrm{A}}, {\mathrm{r}}_{\mathrm{B}}=2.8\stackrel{°}{\mathrm{A}}$
