The metals used in jewellery are always chosen for their reactivity; platinum, gold, and silver are the most common metals used.
Explanation:
- Platinum and, gold are low reactive metals that corrode infrequently (in silver) and retain their brilliance, they are used to make jewellery.
- Tarnish, rust, and corrosion do not affect gold.
- Because of its excellent properties and lustre, gold is the most important metal in the production of jewellery.
- Because pure gold is too soft to be used in everyday life, it is alloyed with a variety of metals to make it more durable and acceptable for use in jewellery.
- Because gold and platinum do not tarnish easily when exposed to air or other nonmetals, this is the primary reason.
