Which element will form an ion whose ionic radius is larger than its atomic radius?
Since there is a question like that, I’ll say anyone of them can be a ion, and remember the negaive ion’s radius is always laeger than is its atomic radius, and positive ion’s radius is always smaller than its atomic, due to the attraction force from the nuclear.In this question K, Li, Mg will always become positively charged ions, thus there ionic radii are always smaller than thier atomic, and F tends to gain a eletcron, thus has a neagtive charge, will have a greater radius.
