Detailed Solution

The above statement is true.
Some materials have a shiny appearance and so they are said to be lustrous. The metals react with the gases present in the atmosphere like hydrogen, oxygen, hydrogen sulphide etc., which is the reason why some metals lose their shine when exposed to the atmosphere. Gold is a highly unreactive metal and it remains unaffected by air, water and any other gas in the atmosphere so it does not get dull or lose its shine. Silver reacts with gases present in the atmosphere like hydrogen sulphide and on long exposure to moist air loses its shine and becomes dull. So, an old silver spoon appears dull while gold earrings appear lustrous.
