- 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 known; francium has properties similar to caesium.
The chemistry of francium is practically unknown.
francium is commonly found as hard rock unless it comes from gravestones
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
yes
Francium has a long and interesting history of discovery, difficult to be described on WA.For details see this link.

1. Francium is the most reactive metal.2. The estimated melting point is 30 oC.
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 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.
