Question

Why do gold and plantinm not qurd in moist air?

Answer 1

because these both are very less reactive

Answer 2

Explanation:

Gold and platinum are very least reactive materials and do not react with air and moisture easily. Because gold is extracted in pure form and doesn't have any need to go into chemical industries like other materials.

Another reason is, any metal reacts with air with chemical bonds but the valency of gold is +1 and for air -2, which does not make a perfect bond. t

Thus gold and platinum do not react with air easily.
