A crystal structure has a face-centered cubic (FCC) arrangement of atoms A and atoms B occupy all the octahedral voids. If the atoms A are removed, what is the resulting lattice type for atoms B?

A pure crystalline substance, on being heated gradually, first forms a turbid looking liquid and then the turbidity completely disappears. This behavior is the characteristic of substances forming

The edge of unit cell of fcc Xe crystal is 620 pm. The radius of Xe atom is

Which has no rotation of symmetry?

Lithium borohydride crystallizes in an orthorhombic system with 4 molecule per unit cell. The unit cell dimensions are $a = 6.8\mathop {\rm{A}}\limits^ \circ ,b = 4.4\mathop {\rm{A}}\limits^ \circ \;and\;c = 7.2\mathop {\rm{A}}\limits^ \circ$. If the molar mass is 21.76, then the density of crystals is :
