because the iron bonds with oxygen, so the weight becomes the original weight of iron plus the original weight of Oxygen.
Iron gets heavier as it rusts, because it bonds with the oxygen in the air, adding mass to the iron.
Because oxygen molecules have bonded with the iron and added their weight to the mass.
When the iron rusted, it reacted with oxygen to form iron oxide, which is rust. So, the new mass is the original iron plus the mass of the oxygen that combined with it.

Iron rusts in the presence of Oxygen.
Neither. Only iron rusts. Other metals oxidize.

No. Atoms cannot be destroyed by chemical processes. When iron rusts it bonds with oxygen to form iron oxide.
iron oxide
Iron rusts in the presence of Oxygen.

It rusts. Check the "related links" if you are concerned for more information regarding the chemical reactions that take place and the different products formed when iron rusts.

Talking about Iron. Rust is an oxide of Iron. Basically Iron that rusts has captured Oxygen from the air around it in a chemical reaction - a slow one thankfully! The weight increase is due to the attached Oxygen.
No. Atoms cannot be destroyed by chemical processes. When iron rusts it bonds with oxygen to form iron oxide.

No. Iron rusts but it is not biodegradable.
When iron (Fe) rusts, it combines with oxygen (O2) to form various forms of iron oxide such as Fe2O3, Fe3O4, or FeO2. In each of these there are oxygen molecules bonded to the iron. The oxygen comes from the air, water or other solution. So an object which was formally pure iron, once rusted, will contain additional mass from the oxygen and weigh more than it did before.
