Hydrogen reacts with strong metals to form metal hydrides.

Answer

To determine whether the statement "Hydrogen reacts with strong metals to form metal hydrides" is true or false, we can analyze the reaction of hydrogen with various metals.

### Step-by-Step Solution:

1. **Understanding Metal Hydrides**:
- Metal hydrides are compounds formed when hydrogen reacts with metals. They typically consist of a metal bonded to hydrogen.

2. **Identifying Strong Metals**:
- Strong metals, often referred to as alkali metals (like sodium and potassium) and some alkaline earth metals, readily react with hydrogen.

3. **Examples of Reactions**:
- **Sodium and Hydrogen**: When sodium (Na) reacts with hydrogen (H₂), it forms sodium hydride (NaH).
- **Potassium and Hydrogen**: Similarly, potassium (K) reacts with hydrogen to form potassium hydride (KH).
- **D-Block Elements**: Some transition metals, such as chromium (Cr), can also react with hydrogen to form metal hydrides, like chromium hydride (CrH).

4. **Conclusion**:
- Since hydrogen reacts with strong metals to form metal hydrides as shown in the examples, the statement is indeed **true**.

### Final Answer:
The statement "Hydrogen reacts with strong metals to form metal hydrides" is **True**.
