Summary. When a metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide. Rust is a form of iron oxide and it forms slowly when iron is exposed to air.
Does every metal react with oxygen?
All metals react with oxygen except silver (Ag(s)), platinum (Pt(s)) and gold (Au(s)). In general, metals react with oxygen to form metal oxides.
What metals Cannot react with oxygen?
- The noble metals are the ones that do not react with oxygen gas and do not get corroded. The metals like Gold, Platinum, Silver, Ruthenium, etc are the examples of noble metals. - So, Platinum whose chemical symbol is Pt does not react with oxygen. - The other metals given in the options are Zinc, Titanium and Iron.
