francium is commonly found as hard rock unless it comes from gravestones
The chemistry of francium is practically unknown.
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
Francium is highly reactive and unstable, making it dangerous to handle. It has a short half-life, which limits its practical use. Additionally, francium is rare and expensive to produce, making it impractical for widespread applications outside of controlled laboratory settings.
The compound FrF2 is named francium difluoride. It consists of one francium (Fr) atom and two fluorine (F) atoms. Francium is an alkali metal, and this compound is expected to exhibit properties similar to other alkali metal fluorides, although it is highly radioactive and rare.
Francium was discovered in 1939, several decades after Mendeleev created his periodic table in 1869. At the time Mendeleev developed his table, francium had not yet been identified, and elements were organized based on their known properties and atomic weights. Additionally, francium is a highly radioactive and unstable element, which made it difficult to study and include in early classifications of elements.
The chemistry of francium is not known; francium has properties similar to caesium.
The chemistry of francium is practically unknown.
- francium is extremely radioactive- the total quantity of francium on the Earth is approx. 30 g- the chemical and physical properties of francium are only estimated, not measured
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
yes

1. Francium is the most reactive metal.2. The estimated melting point is 30 oC.
Francium is a highly reactive metal that is extremely rare and unstable. It is also radioactive, which makes it dangerous to handle. Due to these properties, francium is not commonly used in everyday applications.
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.
Francium is a highly reactive metal that is typically kept in a sealed container due to its extreme rarity and radioactivity. Due to its properties, it is unlikely that anyone has tasted francium.
Because francium was obtained only in very small samples, insufficient for the determination of physical properties.
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
