Is it correct to say that hydrogen can behave as a metal? If it is correct, mention the conditions under which such behaviour is possible.

Explanation

### Step-by-Step Solution:

1. **Understanding Hydrogen's Behavior**:
- Hydrogen is primarily known as a non-metal. However, under certain conditions, it can exhibit properties similar to those of metals.

2. **Formation of H⁺ Ion**:
- Hydrogen can lose an electron to form a hydrogen ion (H⁺). This loss of an electron is a characteristic behavior of metals, which tend to lose electrons to form positive ions.
