Francium hydroxide is a hypothetical inorganic compound with a chemical formula Fr O H. It is a hydroxide of francium . It probably can be produced by reacting francium metal with water : [ 1 ]
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Francium nitrate, sulfate, hydroxide, carbonate, acetate, and oxalate are all soluble in water, while the iodate, picrate, tartrate, chloroplatinate, and silicotungstate are insoluble. The insoluble compounds are used to extract francium from other radioactive products, such as zirconium , niobium , molybdenum , tin , and antimony , using the ...
Francium-223 is the most stable isotope, with a half-life of 21.8 minutes, [8] and it is highly unlikely that an isotope of francium with a longer half-life will ever be discovered or synthesized. [22] Francium-223 is a fifth product of the uranium-235 decay series as a daughter isotope of actinium-227; thorium-227 is the more common daughter. [23]
The alkali metals also react with water to form strongly alkaline hydroxides and thus should be handled with great care. The heavier alkali metals react more vigorously than the lighter ones; for example, when dropped into water, caesium produces a larger explosion than potassium if the same number of moles of each metal is used.
The water hits the hot grease and quickly expands into a huge flame -- i.e., not what you were going for. This Is What Happens When You Throw a Water Bottle Into Molten Steel Source: Gregory Kroll ...
However, it would appear that francium perchlorate has been formed, as it coprecipitates with caesium perchlorate, and several other insoluble francium salts are similarly known (Hyde, E.K., Radiochemical Methods for the Isolation of Element 87 (Francium), J. Am. Chem. Soc., 1952, 74, 4181) The article also quotes a value for the Pauling ...
But in a periodic table in a Next Generation episode, it is shown as an element with chemical symbol Dt and atomic number 87, which is in reality francium. Star Trek: The Next Generation Technical Manual gives a chemical formula made of real and fictional elements, instead of treating dilithium as its own element. Divinium (E115) Call of Duty
