Sir Zn layer break hony k bad b q iron rusting nae hogi

[@shayanabbasigenious4521]

If the zinc coating is broken, the galvanized object remains protected against rusting because zinc is more reactive than iron and hence can be easily oxidized. Thus when the zinc layer breaks down, the zinc continues to react and get oxidized. Hence iron object is protected.
