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

In a reactivity series, the metal on the top is the most reactive while the metal at the bottom is least reactive. thus, $K$ which is least reactive is most likely to occur in a free state in nature.
