Answer:
Sodium is ur answer because a freshly cut sodium metal has a bright, shiny surface due to the oscillations of free electrons that quickly becomes a dull grey as it reacts with oxygen in the air around it. Over time, the metal becomes covered with a white crust of sodium oxide that prevents further reaction of the metal and oxygen.
