WebIonic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard … Webreagents. Rather than wandering oﬀ as solvated cations and acting as uninvolved spectators, the metals, rather than the anion moieties, can initiate and govern the subsequent reactions. To the founders of this ﬁeld, e. g. Grignard, Ziegler, Gilman, Wittig, and their followers, the metal was critical.
