Answer:
Sodium reacts with the oxygen in air to form sodium oxide, and traces of yellowish sodium peroxide. Probably, the reaction with atmospheric oxygen will be faster, because I have never seen sodium metal turning whitish on exposure, though it does lose its lustre and and reactivity (just the surface).

Answer:
Because to the ossilation of free electrons
Explanation:
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.
