Oxygen in the air reacts with the iron, making a reddish brown compound known as iron oxide. Iron is a transition metal and we havent covered them in chemistry yet so i dont know exactly why but i think the iron atom takes two oxygen's electrons to fill its outer shell.

What will happpen to iron nails in bleach?
I did an experiment on this in 4th grade. When I put iron nails in bleach, the nails turned a reddish hue at first, then faded to a brown. This is because of oxidation. The bleach stimulates the ions in the iron, causing them to swirl in a circular motion, thus creating the reddish brown color.
