Ionic Radius Of Lithium. Ionic radius of hydride ion: Ok so what is the ionic radius of a lithium ion?

Although neither atoms nor ions have sharp boundaries, it is useful to treat them as if they are hard spheres with radii. Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. (2) the migration energy barrier of ni gradually decreases due to an increase in concentration of li.
