Classify each of these substance as metals, giant ionic structures or simple molecular structures.
Explanation:
Substance A and C is simple molecular compound.
Substance B and E: Ionic compounds
Substance D: metallic solid.
Ionic compounds constitute of oppositely charged ions bonded by electrostatic forces of attraction.
They are non conductors of electricity in solid state but conduct electricity in aqueous form or molten form.
Molecular solids:
They are bonded by either non polar, polar or hydrogen bonds.
They remain non conductors of electricity at all states.
Metallic solids:
The constituent particles of metallic solids is positive metal ion in sea of free or mobile electrons.
They have very high boiling and melting points.
They are very good conductors.
