Rubidium-87 has an atomic mass of 86.9091835 u, and a binding energy of 757,853 keV. Its atomic percent abundance is 27.835%, and has a half-life of 4.92 ...
Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [9] Rubidium is the first alkali metal in the group to have a density higher than water.

For stable elements, the formal standard atomic weight (s.a.w.) is added, as published by CIAAW. When the s.a.w. is in interval-notation, its conventional value is added too. Data is retrieved from central s.a.w. values lists, formatting is by {{Infobox element/standard atomic weight format}} (same as {{infobox element}}). Example:

He has pledged mass deportations of people who entered the country illegally and sweeping, across-the-board tariffs on all imports worldwide. Nevertheless, the implications for the American ...
The nonprofit American Immigration Council estimates the tally for Trump’s mass-deportation plans could be upwards of $300 billion. Trump is likely to seek funding from Congress, according to aides.
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow. Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
