Webb3 sep. 2009 · For uniformity we have assigned an intensity of 1000 to the strongest line (s) of each spectrum. In most cases the chosen line (or lines) can reasonably be regarded as the ultimate line ( Sec IV ). The relative intensities for most spectra here are based on values from [ RCWM80 ]. Rubidium is the chemical element with the symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. Rubidium is the first alkali metal in the group to have a density higher than water.
