WebVarious isotope standards are used for reporting isotopic compositions; the compositions of each of the standards have been defined as 0‰. Stable oxygen and hydrogen isotopic ratios are normally reported relative to the SMOW standard ("Standard Mean Ocean Water" (Craig, 1961b)) or the virtually equivalent VSMOW (Vienna-SMOW) standard. WebChemical properties It combines easily with other chemical substances at high temperatures It does not usually react with other elements at room temperature It is highly flammable and burn with a blue flame A mixture of hydrogen and oxygen explodes when lit It reacts with oxides and chlorides of many metals to produce free metals It reacts slowly with oxygen …
Rubidium - Element information, properties and uses Periodic Table
Webisotopes of polonium are known, none of which are stable. Its four longest lived isotopes are: polonium-206 (8.8 days), polonium-208 (2.898 years), polonium-209 (102 years), and polonium-210 (138 days). Polonium-210 is the predominant naturally occurring isotope and the one most widely used. WHAT IS POLONIUM-210 USED FOR? birchwood pharmacy north walsham
