Question

halogens are good oxidising agent

Answer 1

Oxidising agents are which reduce them selves and oxidise others.

As halogens have one electron less than octet,they can easily capture one electron,which is the character of good oxidising agents.

Answer 2

Halogens are strong electronegative ions with high negative electron gain enthalpy.

Therefore they have higher tendency to gain electron. That's why they are excellent oxidizing agents.
