Answer from: solikhalifeoy3j1r

Similarities:

1. Electrostatic attraction between particles of unlike charges. occurs in both ionic compounds and metals

2. Both involve metallic cations. Metallic cations are present in both ionic compounds and in metals.

3. Both ionic compounds and metals have a crystal lattice structure in their solid state.

4. Both ionic compounds and metals have high melting and boiling points

5. Both can conduct electricity although ionic compound do so only in molten or solution form.

Differences:

1. The crystal lattice of an ionic compound consists of two oppositely charged ions of two or more elements whereas metals lattices consists of metal cations and delocalised electrons of the same metal.

2. Ionic compounds are compounds whereas metals are elements.

3. Ionic compounds are brittle whereas metals are malleable and ductile.

4. Electrons are transferred from one atom to another in ionic compounds whereas in metals, are delocalised around metallic cations

5. Metals are sonorous and are shiny whereas ionic compounds are not.

Importance of ionic compounds and metals

Ionic compounds are important as salts in industries, as food additives, in detergent and soap-making, as electrolytes and in biochemical systems.

Metals are important in building and construction industry, in jewellery, as conductors in wires and electrode plates, in making parts for vehicles used in transportation

Common ionic compounds and their uses:

Sodium chloride, Potassium iodide and Sodium fluoride are used as a food additive and preservative, as electrolytes, as well as in toothpastes for healthy teeth.

Common metals and their uses

Iron, Aluminum and Gold are used in steel production, making many cooking utensils and for making jewelleries

Common ionic compounds and their uses:

Sodium chloride: sodium chloride is an ionic compound composed of sodium and chloride ions. It is commonly used as a food additive and preservative, as an electrolyte, as well as the extraction of sodium metal.

Potassium iodide: it is composed of potassium and iodine ions. It is added to “iodized” salt to prevent goitre.

Sodium fluoride: it consists of sodium and fluoride ions. It is an important ingredient in toothpaste for healthy teeth.

Common metals and their uses

Iron; iron is used in steel production which is used for constructing bridges, houses, and various machinery parts

Aluminum: it is used in making many cooking utensils like pots and pans

Gold: it is used in making jewelleries and ornaments.
