Ionic radii of v2+

WebCations with larger charges are smaller than cations with smaller charges (e., V2+ has an ionic radius of 79 pm, while that of V3+ is 64 pm). Proceeding down the groups of the … WebWhen the ionic radius Rion of H 3 O + (141 pm) is assumed to be rs, the c value is 4.8 for H 2 O. Following the classical relation, c value is either 4 nor 6, then the rs values are 168 or 112 pm for 4 or 6, respectively. The estimate of c = 4.8 of H 2 O is tentative, but we will use this value in our discussion.
