Give reasons: Aluminium is a highly reactive metal,yet it is used to make utensils for cooking.

(N/A) Although aluminium is a highly reactive metal,it is resistant to corrosion.
This is because aluminium reacts with oxygen present in the air to form a thin,protective layer of aluminium oxide $(Al_2O_3)$.
This oxide layer is very stable and non-porous,which prevents further oxidation and corrosion of the underlying metal.
Additionally,aluminium is lightweight,durable,and an excellent conductor of heat,making it an ideal material for manufacturing cooking utensils.
