Answers :

Metals such as gold, silver, copper and aluminium are among materials that have this quality.

Reason ;

The metals lose their shine on brightness on keeping in air for a long time due to formation of a thin layer of oxide, carbonate or sulphide on their surface by the slow action of various gases present in air.
