what ionic charge does rubidium have
What is the ionic charge of a sulfate ion? Which has a larger ionic radius a strontium ion or a rubidium ion? Both are ions and we should consider the ionic radius, not the atomic radius. Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+). Both ions have â¦the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.
