Close Packing in Crystal (i) 1D - Close Packing,(ii) 2D - Close Packing,(a) Square Close Packing, (b) Hexagonal Close Packing,(iii) 3D - Close Packing Seven Types OF Crystal System (Trick to Remember)

Assertion (A) : The size of a cation is larger in TV than in OV . Reason (R ) : Cations occupy more space than anions is crystals packing.

Statement -1:There are 6 atoms of Mg for unit cell of its crytal. Statement-2: Mg forms HCP lattice. Statement-3: Packing fraction of Mg crystal is 0.74.

A crystal is made of particles A and B. A forms FCC packing and B occupies all the octahedral voids. If all the particles along the plane as shown in figure are removed, then the formula of the crystal would be :

Assertion (A) : CsCl crystal, the coordination number of Cs^(o+) ion is 8 . Reason (R ) : Cl^(ɵ) ion in CsCl adopt bcc type of packing,
