Among the following statements, choose the correct statements.
A. In Ionic solid, ions are the constituent particles. B. Ionic solids are soft.C. Ionic solid are electrical insulators in the solid state. D. Ionic solid conduct electricity in molten state. E. Ionic solid have low melting and boiling points. Choose the correct answer from the options given below:
Among the following statements, choose the correct statements.
Choose the correct answer from the options given below:
A. C & D only
A. D & E only
A. B & C only
A, C & E only
The Correct Option is A
Solution and Explanation
The correct answer is A. C & D only.
Statement A is correct: In an ionic solid, ions are the constituent particles.
Statement C is correct: Ionic solids are electrical insulators in the solid state. The ions are held in a rigid lattice structure, and there are no freely moving charged particles to conduct electricity.
Statement D is correct: Ionic solids can conduct electricity in the molten state or when dissolved in water. In these states, the ions are free to move and carry electric charge.
Therefore, the correct answer is A. C & D only.

Solid State
Solids are substances that are featured by a definite shape, volume, and high density. In the solid-state, the composed particles are arranged in several manners. Solid-state, in simple terms, means "no moving parts." Thus solid-state electronic devices are the ones inclusive of solid components that don’t change their position. Solid is a state of matter where the composed particles are arranged close to each other. The composed particles can be either atoms, molecules, or ions.
Types of Solids:
Based on the nature of the order that is present in the arrangement of their constituent particles solids can be divided into two types;
- Amorphous solids behave the same as super cool liquids due to the arrangement of constituent particles in short-range order. They are isotropic and have a broad melting point (range is about greater than 5°C).
- Crystalline solids have a fixed shape and the constituent particles are arranged in a long-range order.
