Answer 2

Answer:

This phenomenon is commonly referred as rusting. ( Although commonly used for iron). The metal reacts to different components present in air, the one majorly being oxygen. So since the silver is old and the earrings being new, and polished, shines while the spoon does not....we can make it shine again by galvanizing which will retain its shine.....hope this helps you mate......
