Question

the reason why certain metals are available in native form is ​

Answer 1

Answer:

A native metal is any metal that is found pure in its metallic form in nature,since they can resist naturally occurring chemical reactions such as oxidation and reduction.

Only gold, silver, copper and the platinum metals occur in nature in large amounts. Over geological time scales, very few metals can resist natural weathering processes like oxidation, which is why generally only the less reactive metals such as gold and platinum are found as native metals.
