Embibe Experts Solutions for Chapter: Solid State, Exercise 2: Level 2

Choose the correct statements:

Copper crystallises in a structure of face centerd cubic unit cell. The atomic radius of copper is $1.28 \mathrm{A}$. What is axial length on an edge of copper.

If the radius of a metal atom is $2.00 \mathrm{A}$ and its crystal structure in cubic close packed ($\mathrm{FCC}$ lattice), what is the volume (in ${\mathrm{cm}}^3$ ) of one unit cell?

Which one of the following schemes of ordering closed packed sheets of equal sized spheres does not generate closed packed lattice?

If the anions $\left(\mathrm{A}\right)$ form hexagonal closest packing and cations $\left(\mathrm{C}\right)$ occupy only $2/3$ octahedral voids in it, then the general formula of the compound is

Match list-$\mathrm{I}$ with list-$\mathrm{II}$ and select the correct answer by using the codes given below _______.

Codes.

The radius of ${\mathrm{Ag}}^{+}$ ion is $126$ pm and that of ${\mathrm{I}}^{-}$ion is $216$ pm. The co-ordination number of ${\mathrm{Ag}}^{+}$ ion is.

The ionic radii of ${\mathrm{Rb}}^{+}$ and ${\mathrm{I}}^{-}$ are $1.46 \stackrel{\circ }{\mathrm{A}}$ and $2.16 \stackrel{\circ }{\mathrm{A}}$. The most probable type of structure exhibited by it is _______.
