You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity, melting and boiling points, and density. (A) Fermi sphere at T = 0 for a trapped Fermi gas in which all states within a radius of k F are occupied. Rubidium itself might have been considered to be unremarkable as an element until it was used to demonstrate a new state of matter in 1995. The atomic radius is the distance from the atomic nucleus to the outermost stable electron of a neutral atom. In practice, the value is obtained by measuring the diameter of an atom and dividing it in half. not enough information. 161 pm. Up to date, curated data provided by Mathematica 's ElementData function from Wolfram Research, Inc. ... the ionization potential and the electronegativity decrease and the atomic radius increases. Chemical symbol for Rubidium is Rb. The rubidium version of the atomic clock employs the transition between two hyperfine energy states of the rubidium-87 isotope. Notes on the Specific Heat of particular elements: Hydrogen: Value given for gas phase of H .2 Helium: Value given for gas phase. Ok so what is the ionic radius of a Rubidium ion? 15. Atomic radius is the distance from the atom’s nucleus to the outer edge of the electron cloud. The chemical symbol for Rubidium is Rb . Rubidium has an atomic radius of 248 picometers.
