Question

If A, B, C, D, E, F, G, H, I, J and K represent metals in the decreasing order of their reactivity, which one of them is most likely to occur in a free state in nature?

Answer 1

The metal K is most likely to occur in a free state in nature because it is placed at the very end of the decreasing order of the reactivity series. Since it is the least reactive metal, it does not easily react with oxygen, moisture, or acids in the air to form compounds, allowing it to remain in its pure, elemental form.
