Answer

To solve the question regarding the reactivity of atomic hydrogen compared to nascent hydrogen, we will break down the assertion and reason provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding the Types of Hydrogen:**
- There are three forms of hydrogen: atomic hydrogen, nascent hydrogen, and molecular hydrogen.
- Atomic hydrogen consists of individual hydrogen atoms (H).
- Nascent hydrogen refers to hydrogen that is in its newly formed state and is represented as [H].
- Molecular hydrogen is the stable form of hydrogen, represented as H₂.

2. **Stability of Hydrogen Forms:**
- The stability of these forms of hydrogen can be ranked as follows:
- Molecular hydrogen (H₂) is the most stable.
- Nascent hydrogen ([H]) is less stable than molecular hydrogen.
- Atomic hydrogen (H) is the least stable and most reactive.
- Therefore, the order of stability is: H₂ > [H] > H.

3. **Energy Content and Reactivity:**
- Energy is inversely proportional to stability. This means that the less stable a form of hydrogen is, the higher its energy content.
- Consequently, the order of energy content is: Atomic hydrogen (H) > Nascent hydrogen ([H]) > Molecular hydrogen (H₂).
- Since higher energy corresponds to higher reactivity, we can conclude that atomic hydrogen is more reactive than nascent hydrogen.

4. **Evaluating the Assertion and Reason:**
- The assertion states that "Atomic hydrogen is more reactive than nascent hydrogen." This is true based on our analysis.
- The reason states that "The energy content of atomic hydrogen is more than nascent hydrogen." This is also true, as we established that atomic hydrogen has a higher energy content than nascent hydrogen.

5. **Conclusion:**
- Both the assertion and the reason are true.
- Additionally, the reason correctly explains the assertion, as the higher energy content of atomic hydrogen accounts for its greater reactivity.

### Final Answer:
Both the assertion and reason are true, and the reason is a correct explanation for the assertion.
