Question

properties of giant ionic compounds

Answer 1

Answer:

Physics is the natural science that studies matter, its motion and behavior through space and time, and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.

Answer 2

hello Dost ☺

Answer :

Properties of ionic compounds

1. Physical nature:solid and hard due to strong force of attraction. (generally brittle)

2. Melting point and boiling point:have high M.P and B.P, as large amount of heat energy is required to break strong ionic attraction.

3. Solubility: soluble in water and insoluble in kerosene and pertrol.

4. Conduction of electricity:ionic compounds in solid state- does not conduct electricity.

Reason—Ions can not move due to rigid solid structure. Ionic compounds conduct electricity in molten state.
