Ask EduPadi AI for a detailed answer
Correct Option: D
The correct answer is noble metals. Here's why:
- Noble metals: Metals that are resistant to corrosion and oxidation. This is why they are found in their elemental form (uncombined) in the earth's crust. Silver and Gold are classic examples.
- Corrosive metals: Undergo corrosion (breakdown) and do not exist in their free state.
- Reactive metals: Readily react with other substances and are not found in their free state.
- Natural metals: Not a scientific term.
