Explain ii) Ionic solids are hard and brittle.

Ionic radii are

Ionic radii of

Define Ionic Bond?

Explain how vacancies are introduced in an ionic solid when a cation of higher valence is added as an impurity in it.

A particular solid is very hard and has very high melting point. In solid state, it is a non - C0nductor and its melt is a C0nductor of electricity. Classify the solid

Explain why pure liquids and solids can be ignored while writing the equilibrium constant expression?

Assertion (A) :KCl is more likely to show Schottky defect, while Lil is more likely to show Frenkel defect. Reason(R): Schottky defects is more likely in ionic solids in which cations and anions are of comparable size while Frenkel defect is more likely in which cations and anions have large differences in their ionic sizes.

Diamond is hard because
