Which type of elements take part in the bond formation ?

Answer

To answer the question "Which type of elements take part in bond formation?", we can break it down into a step-by-step explanation.

### Step-by-Step Solution:

1. **Understanding Bond Formation**:
- Bond formation occurs when atoms interact to achieve a more stable electron configuration. This can happen through the sharing or transfer of electrons.

2. **Types of Elements**:
- Elements that take part in bond formation can be either **similar (same)** or **dissimilar (different)**.

3. **Example of Similar Elements**:
- Consider the example of **Hydrogen (H2)**:
- Each hydrogen atom has one electron.
- When two hydrogen atoms come together, they share their electrons.
- This sharing leads to the formation of a covalent bond, resulting in the H2 molecule.
- Here, both elements (hydrogens) are the same.

4. **Example of Dissimilar Elements**:
- Now, consider the example of **Hydrogen Chloride (HCl)**:
- Hydrogen has one electron, while Chlorine has seven electrons in its outer shell.
- When hydrogen and chlorine come together, hydrogen shares its electron with chlorine.
- This allows hydrogen to complete its duplet and chlorine to complete its octet, forming a covalent bond.
- In this case, the elements involved are different (hydrogen and chlorine).

5. **Conclusion**:
- Therefore, bond formation can occur between both similar elements (like H2) and dissimilar elements (like HCl).

### Final Answer:
Both similar and dissimilar elements take part in bond formation.
