WebThe atomic radius (r) of an atom can be defined as one half the distance (d) between two nuclei in a diatomic molecule. Atomic radii have been measured for elements. The units for atomic radii are picometers, equal to 10 −12 meters. As an example, the internuclear distance between the two hydrogen atoms in an H 2 molecule is measured to be 74 pm. WebThe ionic radius is generally calculated by estimating the distance between the two nuclei and dividing it according to the atomic sizes. It is measured in picometer (pm) or nanometer (nm) unit [1,2]. Ionic Radius Ionic Radius vs. Atomic Radius An ionic bond is formed when one atom donates electrons to the other, resulting in ions.

"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. " - Ionic radius unit of measurement
