The flame colours of metal ions are due to:

The crystalline structure of $$NaCl$$ is:

$$KBr$$ crystallises in $$NaCl$$ type of crystal lattice and its density is $$2.75 g/cm^3$$. Number of unit cells of $$KBr$$ present in a 1.00 $$mm^3$$ grain of $$KBr$$ are:

Interstitial hole is called tetrahedral because:

Fraction of the total octahedral voids occupied will be:

In a face-centre cubic arrangement of A and B atoms whose A atoms are at the corner of the unit cell and B atoms at the face-centre, one of A atom is missing from one corner in the unit cell. The simplest formula of the compound is:

A metal crystallizes face-centered cubic lattice with the edge length of $$450\ pm$$. Molar mass of the metal is $$50\ g\ mol^{-1}$$. The density of metal will be:
