Give a reason for the following:

Silver, gold and platinum are used to make jewellery.

Answer 1

1. Gold, silver, and platinum are the least reactive metals. They do not react with air, water, acids, alkalis, or other gases in the environment, so their shine lasts for years.
2. Due to their bright lustre and resistance to corrosion, gold, silver, and platinum are used to make jewellery.
