Although this element can be considered as the natural element, but the amount of this element is very rare in the earth. Francium element is the second rarest natural element after astatine. Home » Chemistry » Inorganic Chemistry » 4 Francium Element Uses in Everyday Life – Properties. Earlier we learned that francium is one rare element. The main use of this chemical element is for research purposes in the field of chemistry and atomic structure. It is produced both by naturally and by artificial methods. Francium element uses in this method can make this experiment faster without lowering the quality of its experiment result. Because of this its chemical and physical properties are not known. Mme.tutunan Perey then introduced the newer method to determine this Actium element by francium element which is one of Actium’s possible derivative. Disclaimer | This article will cover the francium element uses in limited areas and also its discovery and chemical properties. Before francium element was discovered, Mendeelev, one of the most influencing scientist in chemistry, has predicted that there must be the element like caesium in the periodic table. Francium Element Uses in Atomic Structure Research. This isotope decays into radium-223 through beta decay process or decays into astatine-219 through alpha decay process. There must be detailed research to be conducted to see how this chemical element can be useful in the oncology field. This experiment is conducted by emitting the light from the laser-trapped francium 210Fr ions. Francium is not the popular chemical element which is used extensively in the commercial application. Francium is an element with chemical symbol Fr and atomic number 87 in the periodic table. It has the atomic weight of 223 (from isotope Fr-223). It is naturally present in uranium and consider the second rarest element in the earth crust. Previously, scientist conduct the experiment to determine Actium in nature by making measurement from all 227Ac decay products’ activities. Uses of Francium. Prior to its discovery, it was referred to as eka-caesium. Required fields are marked *. And after Word War II, this discovery was finally confirmed in 1946. It has been used in spectroscopy experiments to learn about coupling constants between subatomic particles and energy levels. You can find Francium naturally in the uranium minerals. It exists in short-lived radioactive forms and cannot be isolated in pure stable form. This chemical element also has the other names like eka-caesium and actinium K. Francium’s main characteristic is its instability and rarity. Francium is the least electronegative of all the known elements. Most probably, it is assumed that about 340-550 gms of this metal francium are found in the earth’s crust. Francium Element Uses in Biological Research. As a prediction, scientist mostly use the chemical properties of Caesium (Cs) and Rubidium (Rb). It is also used in many spectroscopic experiments. Francium is also included in the radioactive metal element. Besides its use in the chemical related research, francium also has the benefit in the biological research. However, it’s still unclear whether this approach can be applied to organism. 1. She successfully found this chemical element while doing analysis in decay sequence of actinium element. The At that time, she had done purifying the Actium from all known radioactive impurities but she still detected the radioactivity emission from another element. The isotopes of francium decay quickly into astatine, radium, and radon. As francium has very short life, this chemical element can be the great choice for Actium element research. In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. This element must have the atomic number of 87 which is placed below caesium in group 1 of periodic table. Francium is a very rare element, with less than 30grams present in the earth. Francium is a heavy, unstable, radioactive metal with a maximum half-life of only 22 minutes. Francium is a highly radioactive metal, and since it exhibits a short half-life, it … The popular use of francium in the chemical research is for defining the Actium element in the natural object. This kind of francium element uses still need further studies and experiments as francium still has some issues like its instability and very short life period. 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. The activity of francium increased in the affected tissue on that rats. 2. Francium is formed by radioactive decay of actinium, and artificially made by bombarding thorium with protons. And more importantly, this new Actium determination method takes significantly less time than the old method. You will see that most of the chemical properties of francium element is similar to caesium which has the position above francium in the periodic table of chemical element. 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. This result of francium experiment is pretty much similar to the prediction from quantum theory. This kind of approach gives scientist enough accuracy in the occurrence of other radioactive elements. Your email address will not be published. It is considered to be the second rarest metal discovered on the earth’s crust next to the. Francium is the second rarest element in the Earth's crust, next to astatine. It is used for diagnostics for curing cancers. The analysis of francium often uses the analogue from its two above elements, caesium and rubidium. Francium is the chemical element with the chemical symbol Fr. In the era of 1920s and 1930s, there were some claims about the discovery of this radioactive element in minerals and new lines of the X-ray spectra, but these claims were lack in the scientific evidences. To do this research, francium should be separated from Actium in 3 hours after it has been isolated from the natural products. Francium.
