Elements that are highly unreactive or noble are often found in the free or native state in nature. Gold (Au) and Platinum (Pt) are known for their low reactivity and are frequently found in their metallic state, not combined with other elements in ores.
Gold and Platinum are noble metals that are highly unreactive and commonly found in the free state.
While Silver (Ag) and Copper (Cu) can sometimes be found in the free state, they are more commonly found in combined forms as ores due to their higher reactivity compared to Gold and Platinum. Gold and Platinum are considered the most likely pair among the options to be primarily found in the free state.
