Web12 de fev. de 2024 · A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O 2 → Fe 2 O 3. The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions. WebPositive and negative ions form when a metal reacts with a non-metal, by transferring electrons. The oppositely charged ions are strongly attracted to each other, forming … WebBased on the above information, some of the key differences between cation and anion are as follows: Cation. Anion. It is a positively charged ion, e.g. Na+, Fe2+, Pb2+ etc. It is a negatively charged ion, e.g. Cl-, F-, OH- etc. It has more protons than electrons. It has more electrons than protons.
