Which process occur in electropositive ion ?

Options

A. Oxidation
B. Reduction
C. Both 1 and 2
D. None of these

Explanation

### Step-by-Step Solution:

1. **Understanding Electropositive Ions**:
Electropositive ions are those that tend to lose electrons easily. They usually have low electronegativity and are typically metals. For example, sodium (Na) is an electropositive ion.

2. **Examining Sodium as an Example**:
Sodium has an atomic number of 11, which means it has 11 electrons. Its electronic configuration is:
- 1s² 2s² 2p⁶ 3s¹
This indicates that sodium has one electron in its outermost shell (3s orbital).

3. **Formation of Electropositive Ion**:
To achieve a stable electronic configuration similar to that of noble gases, sodium can lose its one outermost electron. The stable configuration after losing one electron will be:
- 1s² 2s² 2p⁶ (which is the configuration of Neon, a noble gas).

4. **Oxidation State Change**:
When sodium loses one electron, its oxidation state changes from 0 (in elemental form) to +1. This increase in oxidation state signifies that sodium is undergoing oxidation.

5. **Conclusion**:
Therefore, the process that occurs in an electropositive ion, such as sodium, is **oxidation**.

### Final Answer:
The process that occurs in an electropositive ion is **oxidation**.
