Francium is a rare, highly unstable radioactive element with a short half-life of around 20 minutes. It is mainly used in scientific research and is toxic. It can be found in small amounts in uranium ores and can be artificially created in the laboratory. Its physical properties are not well known. Marguerite Perey discovered it in 1939 and named it after her nation of discovery.
Francium is a radioactive chemical element classified among the alkaline earth metals of the periodic table. It is extremely unstable, with a very short half-life – around 20 minutes – and, as a result, has little application outside the realm of scientific research. Most of the world’s francium is synthesized in laboratories; it appears in nature only in very small traces, and is an extremely rare element. Due to its rarity, consumers are unlikely to interact with francium.
In nature, francium is found in small amounts in uranium ores. When it breaks down, it decays into radium, astatine, or radon. It can also be artificially created in the laboratory from actinium or thorium. Because the element is so short-lived, little is known about its physical properties, although it presumably shares traits with other alkaline earth metals. In the periodic table of elements, francium is identified with the symbol Fr and has atomic number 87.
The existence of this element was hypothesized in the 1800s, but was not isolated and confirmed until 1939. Credit for the element’s discovery goes to Marguerite Perey, who was exploring radioactive elements at the Curie Institute in Paris when she made his discovery. When she was offered the privilege of naming the item, she patriotically named it for her nation of discovery.
This element is mainly used in research, especially in the field of physics. It is also used in spectroscopy experiments to learn more about subatomic particles. Researchers have also experimented with creating longer-lived versions of francium in hopes of learning more about the element or finding potential applications for it. It has been speculated that the element could, for example, be useful in nuclear medicine if researchers can synthesize a stable version of it.
Like other radioactive elements, francium is toxic. Exposure to the element can cause radiation damage in the body, which can lead to long-term health effects or more immediate health problems, depending on the amount of the dosage. People who work with this item typically only see very small amounts, which certainly reduces the risk, but they also take precautions to protect themselves from long-term high dosages.
