It was Paheli’s birthday. Her grandmother gave her two gifts made of metals, one old dull silver spoon and a pair of lustrous gold earrings. She was surprised to see the difference in the appearance of the two metals. Can you explain the reason for this difference?

The silver spoon on long exposure to moist air has lost its shine and appears dull whereas gold does not tarnish.
