Question

Which one is more reactive, Ag or Pt ?

Answer 1

Ag and Pt are non-reactive metals

Explanation:

Both Ag and Pt belong to Class IV metals. Metals in the fourth class are so unreactive they are essentially inert at room temperature. These metals are ideal for making jewelry or coins because they do not react with the vast majority of the substances with which they come into daily contact. As a result, they are often called the "coinage metals."

So both silver and platinum are non-reactive metals. Hence used in making jewelry.
