How beryllium hydride is different from the hydrides of other members of group 2?

Explanation

To understand how beryllium hydride (BeH2) differs from the hydrides of other group 2 elements, we can break down the differences into several key points:

### Step-by-Step Solution:

1. **Nature of Hydrides**:
- Beryllium hydride is **covalent** and **polymeric** in nature.
- In contrast, the hydrides of other group 2 elements (such as magnesium, calcium, strontium, and barium) are primarily **ionic** in nature.
