The type of bond expected to be formed atoms between of two elements in interstitial compounds is

Options

A. Covalent
B. Ionic
C. Metallic
D. None

Answer

To determine the type of bond expected to be formed between atoms of two elements in interstitial compounds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Interstitial Compounds**:
Interstitial compounds are formed when small atoms, such as hydrogen, carbon, or nitrogen, occupy the interstitial spaces (voids) between the larger metal atoms in a metallic lattice.

**Hint**: Consider what types of elements typically form interstitial compounds and their sizes relative to the metal atoms.

2. **Analyzing Bond Types**:
The types of bonds that can be formed between atoms include:
- **Covalent Bonds**: Formed by the sharing of electrons between non-metal atoms.
- **Ionic Bonds**: Formed by the transfer of electrons from one atom to another, typically between metals and non-metals.
- **Metallic Bonds**: Involve a 'sea of electrons' shared among a lattice of metal atoms.
- **Amine Bonds**: Typically involve nitrogen and are not relevant in this context.

**Hint**: Think about the nature of the elements involved in interstitial compounds and how they interact.

3. **Identifying the Bonding Nature in Interstitial Compounds**:
In interstitial compounds, the smaller atoms (often non-metals) form bonds with the metal atoms. These bonds are often characterized by electron sharing, which is indicative of covalent bonding, especially when considering the hybridization of orbitals.

**Hint**: Reflect on how non-metals bond with metals and what type of hybridization occurs.

4. **Conclusion**:
Given the nature of interstitial compounds and the bonding characteristics, the type of bond expected to be formed between the atoms of two elements in interstitial compounds is primarily **covalent**.

**Final Answer**: Covalent bond.
