Which one among the following metals is more reactive than hydrogen ?

Options

A. Mercury
B. Copper
C. Silver
D. Tin

Explanation

To determine which metal is more reactive than hydrogen, we can follow these steps:

### Step 1: Understand the Reactivity Series
The reactivity series is a list of metals arranged in order of decreasing reactivity. The higher a metal is in the series, the more reactive it is. Hydrogen is included in this series for comparison purposes.

### Step 2: Identify the Position of Hydrogen
In the reactivity series, hydrogen is positioned between metals like zinc and copper. Metals that are placed above hydrogen in the series are considered more reactive than hydrogen.

### Step 3: List Metals Above Hydrogen
From the reactivity series, we can identify several metals that are more reactive than hydrogen. Common examples include:
- Sodium (Na)
- Potassium (K)
- Calcium (Ca)
- Magnesium (Mg)
- Aluminum (Al)
- Zinc (Zn)

### Step 4: Choose an Example
Among these metals, we can choose any of them as an example. For instance, zinc (Zn) is a commonly known metal that is more reactive than hydrogen.

### Step 5: Conclusion
Thus, one metal that is more reactive than hydrogen is zinc (Zn).

### Final Answer
Zinc (Zn) is more reactive than hydrogen.
