Halogens strong oxidizing agents. Explain why?

Oxidation is a loss of electrons and the oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons.

The general electronic configuration of halogens is np5, n=2-6. it needs only one more electron to complete the octet and to attain the stable noble gas configuration

They are having electronegativity character also. therefore they have a high tendency to gain an electron and thus act as a strong oxidizing agent.

Fluorine is most powerful oxidizing agent

Oxidizing ability falls as we go down the group.

Eg: 2F2 + 2H2O –> 4HF + O2

Fluorine oxidises water to oxygen and impossible to do simple solution reaction with it
