Sodium forms Na+ion, but it does not form Na2+because ofa)very low val...
Explanation:
Low value of 1st Ionization Energy (IE)
- Sodium has a relatively low value of 1st IE, which means it requires less energy to remove the outermost electron and form Na+ ion.
- The 1st IE of sodium is 495.8 kJ/mol, which is lower compared to other elements in the same period.
High value of 2nd Ionization Energy (IE)
- The 2nd IE of sodium is significantly higher than the 1st IE, making it energetically unfavorable for sodium to lose a second electron to form Na2+ ion.
- The 2nd IE of sodium is 4562 kJ/mol, much higher than the 1st IE.
Formation of Na+ ion
- When sodium loses its outermost electron, it forms a stable Na+ ion with a complete octet electron configuration.
- This stable configuration makes the formation of Na2+ ion unnecessary and energetically unfavorable.
Conclusion
- The combination of a low 1st IE and a high 2nd IE in sodium prevents the formation of Na2+ ion, as it is more favorable for sodium to lose one electron and form a stable Na+ ion rather than lose two electrons to form Na2+ ion.

Na (11) = 1s22s22p63s1
It readily gives one electron to attain stability; thus, the value of 1st IE is less.
Na+ = 1s22s22p6
Second electron has to be removed from completely filled p orbital which requires large amount of energy, i.e. the value of 2nd IE is very large, which makes it difficult to form Na2+ ion.
