Francium: The Elusive and Radioactive Element
Francium, with the symbol Fr and atomic number 87, is a fascinating, yet challenging element to study due to its unique properties:
Extreme Rarity: Francium is the second rarest naturally occurring element on Earth, even scarcer than astatine. Only about 30 grams exist at any given time, making it difficult to isolate and study in larger quantities.
High Radioactivity: All known isotopes of francium are radioactive, meaning their nuclei spontaneously decay into other elements, releasing energy in the form of radiation. The most stable isotope, francium-223, has a half-life of only 22 minutes, meaning it takes 22 minutes for half of the atoms in a sample to decay.
Alkali Metal Characteristics: Despite its rarity and radioactivity, francium belongs to the alkali metal group in the periodic table. This means it shares some properties with its more common cousins like sodium and potassium, such as having a single valence electron and being highly reactive.
Predicted Properties: Due to its extreme rarity, some properties of francium remain unexplored experimentally. However, scientists can predict its behavior based on its position in the periodic table and its electronic structure. For example, francium is expected to be the most reactive alkali metal and have a violent reaction with water.
No Practical Applications: Unfortunately, francium’s short half-life and scarcity render it impractical for any commercial use.
Discovery and Naming: The element was discovered in 1939 by Marguerite Perey in France, hence the name “francium.” It was the last of the naturally occurring elements to be discovered, filling a gap in the periodic table.
Overall, francium remains an enigmatic element in the scientific world, offering a glimpse into the fascinating realm of radioactive elements and the complexities of nature.

Due to its extreme rarity and short half-life, francium cannot be commercially bought or sold in the traditional sense. It doesn’t have a set price per gram like other elements. Here’s why:
- Difficult to Isolate: The scarcity of francium makes its isolation incredibly challenging. Extracting significant amounts for commercial purposes is currently impossible.
- Rapid Decay: Even if isolation were possible, the element’s radioactivity means it would decay rapidly, rendering it practically useless within a matter of minutes.
However, if hypothetically one could produce a gram of francium, its cost is estimated to be in the billions of US dollars. This estimation considers the complex and expensive procedures required for its synthesis, containment, and handling.
It’s important to remember that francium has no practical applications due to its limitations. Therefore, despite its astronomical estimated price, it holds no real market value and isn’t commercially available.
Electronic Configuration of francium
The electron configuration of francium can be written in two ways:
1. Full configuration:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s¹
This detailed configuration showcases the distribution of all 87 electrons of francium across its various orbitals, following the Aufbau principle.
2. Condensed configuration (using noble gas core):
[Rn] 7s¹
This condensed form is a more efficient way to represent the configuration for larger elements like francium. It uses the symbol [Rn] to represent the electron configuration of the noble gas radon (Rn), which has the configuration [Xe] 4f¹⁴ 5d¹⁰ 6p⁶. Essentially, it “borrows” the configuration of radon, which shares the same core electrons as francium, and only shows the remaining electron in the outermost 7s orbital.
Both forms are correct and represent the same electron configuration for francium. The condensed form is typically preferred for its brevity and clarity.
