Ionic radius of boron ion

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. WebIf the radius of K+ ions 132 pm and that of F– ion is 135 pm, what is the shortest K–F ...
