2017221&ensp·&enspPotassium and sodium are at the top of the reactivity series. 2. The alkali metals have the common properties of metals being silverygrey in colour and good conductors of heat and electricity. 3. The alkali metals are unusually soft, and can easily be cut with a knife. They are shiny when freshly cut but quickly go dull

The Principal Series of Potassium, Rubidium, and Cesium in
The principal series of potassium, rubidium, and cesium in absorption have been measured. The doublet finestructure has been resolved out to 17p in potassium, to 26p in rubidium, and to 21p in cesium the doublet finestructure interval varies in each spectrum inversely as the cube of the effective principal quantum number.
Rubidium is a minor component in lepidolite. Kirchhoff and Bunsen processed 150 kg of a lepidolite containing only 0.24% rubidium oxide (Rb 2 O). Both potassium and rubidium form insoluble salts with chloroplatinic acid, but those salts show a slight difference in solubility in hot
Rubidium and potassium levels are altered in Alzheimer's
Loss of intracellular compartmentalization of potassium is a biochemical feature of Alzheimer's disease indiing a loss of membrane integrity and mitochondrial dysfunction. We examined potassium and rubidium (a biological proxy for potassium) in brain tissue, blood fractions and cerebrospinal fluid from Alzheimer's disease and healthy control subjects to investigate the diagnostic

THE PHYSIOLOGICAL BEHAVIOR OF RUBIDIUM AND CESIUM
In terms of their chemical behavior the elements of this series may be separated into two groups, the division falling between sodium and potassium. Potassium, rubidium, and cesium display very similar electrical, chemical, and physical properties, which differ only quantitatively in a welldefined manner.

Potassium, Germanium, and Rubidium Kill Cancer Cells
Mass spectrographic and isotope studies have shown that potassium, rubidium, and especially cesium are most efficiently taken up by cancer cells. Glucose can still enter the cell, but oxygen cannot. The cell thus becomes anaerobic. In the absence of oxygen, the glucose undergoes fermentation to lactic acid. The cell pH then drops to 7 and
