Question

Which of the following pair of metals exists in their native state in nature?

Options

• Ag and Hg

• Ag and Zn

• Au and Hg

• Au and Ag

Answer 1

Au and Ag

Explanation:

Gold (Au) and silver (Ag) are noble metals positioned at the very bottom of the electrochemical reactivity series. Because they are highly unreactive, they do not easily combine with environmental oxygen, moisture, or carbon dioxide to form mineral compounds. Consequently, they frequently occur in nature in their free, elemental, or native state.
