What Does FR Stand For?
FR stands for Francium
FR, or Francium, is a highly radioactive alkali metal with the atomic number 87. It is the least stable of all the first 101 elements on the periodic table and is known for its extreme rarity and short half-life, making it difficult to study. Francium occurs naturally in trace amounts as a result of the decay of actinium-227 and has applications in scientific research, particularly in the fields of nuclear chemistry and physics. Due to its intense radioactivity, Francium poses significant safety risks, necessitating careful handling in controlled environments.
