Question

difference between ionic and covalent compounds

Answer 1

A basic definition of an ionic compound is that they are molecules that consist of charged ions. These ions have opposite (both negative and positive) charges. On the other hand, covalent compounds are non-metals which are bound together, and consist of two electrons that are shared between two atoms

Answer 2

Ionic Compounds :-

• Crystalline solids (made of ions)

• High melting and boiling points

• Conduct electricity when melted

• Many soluble in water but not in nonpolar liquid

Covalent Compounds :-

• Gases, liquids, or solids (made of molecules)

• Low melting and boiling points

• Poor electrical conductors in all phases

• Many soluble in nonpolar liquids but not in water

For extra knowledge :-

An ionic compound is basically formed between a metal and a non-metal because they have large electronegativity difference between them. Metals have a tendency to lose electrons and non-metals have a tendency to gain electrons. So a compound between a metal and non-metal involves transfer of electrons and will be ionic. The compound between two non-metals will be covalent. Example HCl, PCl5 etc are covalent.
