Is it true that aluminum does not rust? This is because in the presence of Oxygen, Aluminum undergoes through oxidation to produce aluminum oxide. This aluminum Oxide protects aluminum from further oxidation (Al+O2_Al2O3) Aluminum has an atomic number 13 with valency 3.  It's valency is 3 because it's first Valency is the combining power of an element. Aluminum is a reactive metal. This is because aluminum shows visible reaction when it comes into contact with atmospheric oxygen, water (moisture), salt solution, acids etc. What's about Iron? Iron actually rust because in the presence of Oxygen, iron rather goes through oxidation to produce Iron oxide. This iron oxide formed does not protect the iron from further deterioration or oxidation hence it will rust.(2Fe+ O2_2FeO) You can bring suggest questions for solution.
