Verified By Collegedunia
The Correct Option is A
Solution and Explanation
- Aluminium forms a thin layer of oxide (Al\(_2\)O\(_3\)) on its surface, which protects it from further corrosion.
- This oxide layer is very stable and prevents the metal from reacting with air and water.
Thus, the correct answer is (A) Aluminium.
- This oxide layer is very stable and prevents the metal from reacting with air and water.
Thus, the correct answer is (A) Aluminium.

Top Questions on Metals and Non-Metals
- Many pure metals like copper, iron and gold are very soft and as such are considered unsuitable for certain uses. Metallic objects around us such as cooking utensils, statues, ornaments, guns etc. are actually not made up of pure metals. Instead of pure metals, alloys are used in the design of most of the useful objects. Making alloys enhances the basic properties of a metal which is the primary constituent (metal) of an alloy.
