Which element is stronger in IE?

Postby Angeline 3E » Thu Oct 24, 2019 2:50 pm

In discussion, TA used Na and Mg to see which element had a higher IE. Just to clarify, Mg it's stronger before it loses electrons. But, once both gain their noble gas configurations (lose their electrons), Na is stronger in IE because it's not as willing to give up an electron?

Yes, Na has a lower first ionization energy than Mg because of the fact that it has a weaker nuclear pull because it has less protons. Then if both lose one electron, Na+ has a much higher ionization energy than Mg+ because it now has a noble gas electron configuration

yes, when an atom is in a noble gas configuration, its valance shell is completely filled which means that it is stable. This is why the ionization energy is going to be extremely high. When the valance shell is filled, the atom is stable, and is not going to want to gain or lose any extra electrons.
