The noble metals________________?
Correct answer: C. Are the lowermost in the electro-chemical series of metals
- A. Are exemplified by Na, K and Li
- B. Do not resist corrosion very strongly
- C. Are the lowermost in the electro-chemical series of metals
- D. None of these
Explanation
Noble metals such as gold, platinum, and silver are very resistant to oxidation and corrosion and are placed toward the less-active, lower end of the usual electrochemical activity series. Sodium, potassium, and lithium are highly reactive rather than noble.
