If same type of atoms are packed in hexagonal close packing and cubic close packing separately, then

The radius of an atom is $300 \mathrm{pm}.$ If it crystallizes in a face-centered cubic lattice, the length of the edge of the unit cell is:

A crystalline solid has $\mathrm{A}$ -ions at the corners and face centres where as ${\mathrm{B}}^{+}$ ions are at the body centre and edge centres of the unit cell. The sim ple formula of the compound will be

Schottky defect in crystals is observed when:

Silicon doped with Arsenic is
