Question

Why only Aluminium oxide forms a coating over the Aluminium metal and no other oxide does so?​

Answer 1

Answer:

Aluminium oxide is responsible for the resistance of metallic aluminium to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of aluminium oxide (4 nm thickness) forms on any exposed aluminium surface in a matter of hundreds of picoseconds.

Answer 2

Answer:

first of all this is a very silly question

ask this to your chemistry teacher

by the way for your answer

Aluminium metal is very reactive , so when the metal is exposed to air , it reacts to form Aluminium oxide

now why only Aluminium??

Bcoz if aluminium reacts then aluminium oxide will only be formed and not any other metal's oxide

don't forget to mark me as the BRAINLIEST

and be sure to ask this to your chemistry teacher

she'll surely slap you and bang you in front of the whole class
