The +2 oxidation state becomes more stable in the first half of the first-row transition elements with increasing atomic number because:
| 1. | s-Orbital is becoming more and more half-filled. |
| 2. | f-Orbital is becoming more and more half-filled. |
| 3. | d-Orbital is becoming more and more half-filled. |
| 4. | p-Orbital is becoming more and more half-filled. |
