Sodium is not observed in +2 oxidation state because of its
Correct answer: B. high second ionization potential
- A. high first ionization potential
- B. high second ionization potential
- C. high ionic radius
- D. high electronegativity
Explanation
Removing the second electron from Na+ to form Na2+ requires significantly more energy. This is because the remaining electron is closer to the nucleus and experiences a stronger electrostatic pull.The high energy needed for this second ionization makes the +2 oxidation state unstable and unlikely for sodium

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
