Oxygen and moisture
Lead and tin corrode slowly because they readily form a protective oxide layer on their surface when exposed to air. This oxide layer acts as a barrier, preventing further oxidation and corrosion of the underlying metal. Additionally, their low reactivity makes them less susceptible to corrosion compared to other metals.
Yes, tin will go corrode and go rusty if left to the elements.
it makes it rust and corrode
Moisture and oxygen.
Metals that corrode in salt water easily include iron and tin.
Tin actually will corrode. It is not actually all that resistant to corrosion. It is, however, less susceptible to corrosion than iron. That may be where the myth that it doesn't rust comes from.
The intramolecular forces are weaker and therefore broken easier than tin which contain metallic bonds. Intramolecular forces are substantially weaker than mettalic.
Tin and lead makes pewter
White metal: "Any of various whitish alloys, such as pewter, that contain high percentages of tin or lead." Yes, but very slowly. Tin and lead and pewter do not corrode easily. Also, the rate would decrease over time, as a layer of oxide would coat the surface preventing further corrosion.
The ozone becomes weaker because of CFC's. They react and weaken CFC's.
it makes it weaker
Tin makes tin cans, and melted tin could make window glass. Also Tin gas been known since ancient times.
