And more importantly, this new Actium determination method takes significantly less time than the old method. Francium is synthesized in the nuclear reaction as follow: This synthesis process is introduced by Stony Brook Physics which can build up francium isotopes with mass of 209, 210 and 211. The only occurrence of francium isotopes in nature are Francium-223 and Francium-221. It has a low melting point (27 °C, 81 °F) and, if enough of it could be accumulated, it would be liquid in a warm room. Uses: Francium is so rare and decays so quickly, it doesn't have any commercial applications. She successfully found this chemical element while doing analysis in decay sequence of actinium element. It’s very hard for the scientists to conduct an experiment in exploring Francium properties both its chemical and physical characteristic with this kind of condition. This result of francium experiment is pretty much similar to the prediction from quantum theory. Natural francium is the result of an alpha disintegration of actinium. Francium is a highly radioactive metal, and since it exhibits a short half-life, it … A radioactive substance, francium has a half-life of 22 minutes. Francium element is the good choice for the special spectroscopy experiments. This isotope decays into radium-223 through beta decay process or decays into astatine-219 through alpha decay process. At that time, she had done purifying the Actium from all known radioactive impurities but she still detected the radioactivity emission from another element. It is also used in many spectroscopic experiments. It is the second-most electropositive element, behind only caesium, and is the second rarest naturally occurring element (after astatine). Francium is the chemical element with the chemical symbol Fr. Because of this its chemical and physical properties are not known. Francium element is the good choice for the special spectroscopy experiments. Francium is a heavy, unstable, radioactive metal with a maximum half-life of only 22 minutes. Unlike many other artificial chemical elements like Pu, Tc, Pm, Np and others, Francium is not able to be obtained in the sufficient amount because the limited life time of its isotopes. Disclaimer | Adchoices | The melting point of francium is approximately 27 degree Celsius while its boiling point is about 680 degree Celcius. 3. Mme.tutunan Perey then introduced the newer method to determine this Actium element by francium element which is one of Actium’s possible derivative. Applications. The electronegativity of Francium is: χ = 0.7. Another francium element uses in chemical field is in atomic structure research. Here are just a few examples of francium… Francium element uses in this method can make this experiment faster without lowering the quality of its experiment result. The francium element, especially 223Fr, can be used in the early detection for sarcoma. It has been used in spectroscopy experiments to learn about coupling constants between subatomic particles and energy levels. The most stable state of this radioactive element is the ion Ft+. It is produced both by naturally and by artificial methods. Required fields are marked *. It is used for diagnostics for curing cancers. This is due to its instability properties and its limited amount in the nature. Francium is extremely rare. The experiment showed that these alkali metal elements accumulated in the rats’ kidney, liver, bladder, gut and saliva.
