Which of the following metals does not react with water at all?

Options

A. Aluminium
B. Silver
C. Gold
D. Both (B) and (C)

Explanation

To determine which of the following metals does not react with water at all, 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. Metals that are higher in the series will react with water, while those lower down will not.

### Step 2: Identify the Metals in the Question
Assume the metals given in the options are: Potassium (K), Sodium (Na), Aluminum (Al), Iron (Fe), Copper (Cu), Silver (Ag), and Gold (Au).

### Step 3: Analyze Each Metal's Reactivity with Water
- **Potassium (K)**: Very reactive, reacts vigorously with water.
- **Sodium (Na)**: Also very reactive, reacts with water.
- **Aluminum (Al)**: Reacts with water, especially when the oxide layer is removed.
- **Iron (Fe)**: Reacts slowly with water, especially with steam.
- **Copper (Cu)**: Does not react with water.
- **Silver (Ag)**: Does not react with water.
- **Gold (Au)**: Does not react with water.

### Step 4: Determine Which Metals Do Not React with Water
From the analysis, Copper (Cu), Silver (Ag), and Gold (Au) do not react with water. However, since the question asks for a specific answer, we can conclude that both Silver and Gold are metals that do not react with water at all.

### Step 5: Final Answer
Among the metals listed, **Silver (Ag)** and **Gold (Au)** do not react with water at all.
