Question

Name the metal that do not corrode easily

Answer 1

Metal such as gold (Au) and platinum (Pt) present at the bottom of the activity series do not corrode easily.

Answer 2

Metals such as gold and platinum have strong resistivity towards corrosion.

• The process of conversion of pure metal to its oxides, or hydrides or sulfides through natural and biological processes is called corrosion.
• When a metal comes in contact with air and water, due to high reactivity it gets corroded.
• The highly reactive metal undergoes corrosion at a faster rate than the low reactive metal.
• As the metal such as gold and platinum are least reactive they are not corroded easily.
