WHy OXygen can react with metal?As i know , oxygen(O2) is bonded by covalent bond and it should be neutral charge. So how can the metal react with oxygen?
Click For Summary
SUMMARY
Oxygen (O2) reacts with metals due to differences in electronegativity, particularly between iron and oxygen, leading to the formation of ionic bonds. The covalent bonds in molecular oxygen break when interacting with iron, resulting in iron oxidation to Fe(OH)3. Additionally, the reaction occurs in the presence of moisture, where a thin aqueous film facilitates the dissolution of iron. In contrast, copper exhibits passive film formation, which inhibits similar reactions.
