द्वितीय आवर्त के तत्त्वों में वास्तविक आयनन एन्थैल्पी का क्रम इस प्रकार है- \( \mathrm{Li}\mathrm{B}\mathrm{Be}\mathrm{C}\mathrm{O}\mathrm{N}\mathrm{F}\mathrm{Ne} \) व्याख्या कीजिए कि (i) \( \mathrm{Be} \) की \( \Delta_{i} H, B \) से अधिक क्यों है?
(i) \( \mathrm{O} \) की \( \Delta_{i} H, N \) और \( \mathrm{F} \) से कम क्यों है?
