IInd Ionisation Energy Of Sodium z Da Energy Required To Remove Electron From Da Stable Octect Configuration Of Na+ Ion…. While… IInd Ionisation Energy Of Mg z Da Energy Needed To Remove Electron From Unstable s1 Configuration.. Hence More Energy z Needed In Da Former Case coz Na+ z Losing Its Stability N Less Energy z Needed In Latter Case coz Mg+ z aquring Stable Octect Configuration After IInd Ionisation…..
