francium

 

[ ˈfrænsɪəm ]

Noun
Context #1 | Noun

chemical element

Francium is a highly radioactive alkali metal with the symbol Fr and atomic number 87. It is the least stable of the first 101 elements on the periodic table and is found in nature only in trace amounts. Due to its extreme radioactivity, it is highly dangerous and mainly of interest for scientific research.

Examples of usage

  • Francium is one of the rarest elements on Earth.
  • The discovery of francium provided insights into atomic structure.
  • Researchers study francium to understand alkali metal properties.

Etymology

Francium was discovered in 1939 by the physicist Marguerite Perey at the Curie Institute in Paris. The element was named after France, reflecting its discovery in that country. It is classified as an alkali metal, falling in Group 1 of the periodic table. Due to its short half-life, francium is not found in significant quantities in nature and is produced via the decay of actinium. Its existence was hypothesized before its discovery, and its properties were predicted based on the behavior of other alkali metals. The element is both chemically and physically unstable. Francium has since become one of the most mysterious elements due to the difficulty in studying it in laboratory settings.
