In 1951 J. M. Bijvoet, A. F. Peerdeman, and A. J. van Bommel showed, using x-ray crystallography, that the absolute arrangement of atoms in space for
sodium rubidium tartarate could be determined.
Bijvoet's absolute structure of
sodium rubidium (+)- tartrate tetrahydrate marked the first time stereochemistry had been determined by experiment (Nature 1951, DOI: 10.1038 / 168271a0).
Breakdown of Macro and Micro Minerals A. Macro Minerals - magnesium, Phosphorus, Calcium, Potassium, chlorine,
sodium, and sulfur B. Microminerals - Iron, zinc, copper, chromium, selenium, iodine, boron, manganese, molybdenum, lithium (used to treat bipolar disorder),
rubidium (required in smaller amounts in the body) 3.
And along with
sodium and potassium, feldspar dust particles are inevitably studded with zillions of
rubidium and cesium atoms as well — Thanx Eli - one begins to understand that it isn't ll physics!
