alleryLess reactive metals like gold, silver and platinum are found in nature mainly in which state?
ACombined nitrate state
BCombined sulphide state
CCombined carbonate state
DFree (native) state
Answer & Solution
Correct answer: D. Free (native) state
1. Metals at the bottom of the reactivity series are least reactive.
2. Being unreactive, they do not readily combine with other elements.
3. Therefore gold, silver and platinum occur in the free (native) state.
4. Combined sulphide or carbonate states are typical of reactive metals, so those are wrong.
