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.

slamgirl [31]

Answer:

Potassium cation = K⁺²

Explanation:

The metal cation in K₂SO₄ is K⁺². While the anion is SO₄²⁻.

All the metals have tendency to lose the electrons and form cation. In given compound the metal is potassium so it should form the cation. The overall compound is neutral.

The charge on sulfate is -2. While the oxidation state of potassium is +1. So in order to make compound overall neutral there should be two potassium cation so that potassium becomes +2 and cancel the -2 charge on sulfate and make the charge on compound zero.

2K⁺²  ,  SO₄²⁻

K₂SO₄
