प्रश्न
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?

उत्तर
The metal K is most likely to occur in a free state in nature because it is the least reactive among other metals. Since it is the least reactive, it will not react with other elements. In a reactivity series, metals are arranged in decreasing order. Since K is placed at the very end of the series, it is the least reactive metal. Because it has very low chemical reactivity, 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.
