Constituent particles of a solid have

A very hard crystalline solid that melts at very high temperature, cannot conduct electricity either in solid state or in molten state. What kind of crystalline solid is this? What type of constituent particles does this solid consist of? What is the nature of forces that holds the particles in this solids?

Based on the nature of order present in the arrangement of the constituent particles, solid are classified into two crystalline and amorphous. List out any four points of difference between crystalline and amorphous solids.

Which of the following statements do not express the properties of a solid? (i) The particles of a solid have high energy. (ii) The interparticle forces of attraction in a solid are very weak. (iii) A solid melts at a fixed temperature. (iv) The fluidity of a solid is very high.

In molecular solid the constituent particles are held together by ____ .

The sharp melting point of crystalline solids compared to amorphous solids is due to a) a regular arrangement of constituent particles observed over a short distance in the crystal lattice. b) a regular arrangement of constituent particles observed over a long distance in the crystal lattice. c) Same arrangement of constituent particles in different directions. d) Different arrangement of constituent particles in different directions.
