### QUESTION 6
Aluminium atoms can bond with oxygen atoms to form aluminium oxide.

6.1.1 Name the type of bond that exists between the particles of aluminium and oxygen. Briefly explain the principle on which this type of bond keeps the particles together.

6.1.2 Use Lewis structures to show the bond formation between aluminium and oxygen. Show all the steps and write down the chemical formula of aluminium oxide.



Answer :

Final answer:

The type of bond between aluminum and oxygen is an ionic bond, forming aluminum oxide with the chemical formula Al2O3 in a process where electrons are transferred to create oppositely charged ions that attract each other, leading to a stable compound.


Explanation:

6.1.1 Type of Bond: The bond between aluminum and oxygen atoms is an ionic bond. This bond is formed based on the attraction between oppositely charged ions, where aluminum gives away electrons to oxygen, resulting in the formation of positively and negatively charged ions that attract each other to form a stable compound.

6.1.2 Lewis Structures and Chemical Formula: Using Lewis structures, aluminum forms 3+ cations by losing three electrons, and oxygen forms 2- anions by gaining two electrons. The chemical formula of aluminum oxide is Al2O3, where two aluminum cations combine with three oxide anions to achieve electrical neutrality.

Aluminum Oxide: Aluminum oxide (Al2O3) is an essential industrial compound used in various applications such as ceramics, abrasives, and antacids due to its properties and abundance.
