Mg2+ and F-

Postby JamieVu_2C » Sat Dec 07, 2019 9:54 pm

How does Mg2+ have a larger radius than F- when F- has a greater effective nuclear charge since it is further to the right on the periodic table and when Mg2+ is in a higher energy shell?

You’ve answered your question in your own post; Mg is lower in the periodic table and thus larger, using one more electron shell than fluorine. This is the case for the ions as well
