Trying to find the right answer to this..

Predict the modes of occurrence of the following three types of metals:

(i) Highly reactive (e.g., Na)
(ii) Moderately reactive (e.g., Fe)
(iii) Noble metal (e.g., Au)

(i) Sodium being highly reactive in nature, it does not occur in free state. It occurs as : NaCl, NaNO₃, Na₂SO₄ and Na₂B₄O₇.10H₂O.

(ii) Iron being moderately reactive in nature, it does not occur in free state. In combined state it occurs as : Fe₂O_3, Fe₃O₄, FeCO₃, FeS₂ and CuFeS₂.

(iii) Noble metal like gold being non-reactive do not occur free in nature.
