Which of the following is most reactive metal?
Which of the following is most reactive metal?
- A. \( F e \)
- B. \( Z \) и
- C. C a \)
- D. \( A l \)
Step-by-step solution
Calcium is an alkaline earth metal and is highly reactive in the reactivity series, more so than iron, zinc, or aluminum. Aluminum forms a protective oxide layer reducing its apparent reactivity, while calcium readily reacts with water and acids.
