Chemistry
1 answer:
andre [41]3 years ago
6 0

Answer: It is reactive

Explanation:

Platinum is the least reactive element on the reactive scale.

For example, the platinum doesn't give the reaction with the oxygen that is found in the air, even though if it is heated but platinum does show the reaction with fluorine, chlorine and at red heat. Platinum can be found in a pure form in nature.

Platinum is reactive, it can react with some elements, but it is the least reactive element and also it is called unreactive, it doesn't easily react with elements.
