Group 2 hydrides with significant covalent character is/are

Explanation

To determine which Group 2 hydrides exhibit significant covalent character, we can analyze the properties of the hydrides formed by the elements in Group 2 of the periodic table. The Group 2 elements include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). The corresponding hydrides are BeH₂, MgH₂, CaH₂, SrH₂, BaH₂, and RaH₂.

### Step-by-Step Solution:

1. **Identify the Group 2 Hydrides**:
The hydrides of Group 2 elements are:
- Beryllium hydride (BeH₂)
- Magnesium hydride (MgH₂)
