What else can I help you with?
What does the element francium look like?
Francium is a highly reactive alkali metal that is a silvery white color in its solid form. It is extremely rare and unstable, so it is usually kept in sealed containers and not readily available for observation. Francium is radioactive and has a very short half-life, making it difficult to study its physical properties in detail.
Why can you not use francium?
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.
What happens when francium and hydrogen combine?
When francium and hydrogen combine, they form francium hydride (FrH), a compound where francium acts as a cation and hydrogen as an anion. Francium is extremely rare and radioactive, making it difficult to study its chemical properties in detail. The compound would likely be highly unstable due to francium's extreme reactivity.
Is francium highly explosive?
No, francium is not highly explosive. It is a highly reactive alkali metal that can react violently with water, but it does not exhibit explosive properties like some other elements. Francium is only found in trace amounts in nature due to its extreme rarity and radioactivity.
What is the light transmission of francium?
Francium is a highly radioactive element that is so rare and unstable that its properties, including light transmission, are difficult to measure accurately. Due to its scarcity and radioactivity, francium is not commonly used for light transmission applications.
What are two interesting properties of francium?
- 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
What is a chemical and physical properties of francium?
1. Francium is the most reactive metal.2. The estimated melting point is 30 oC.
What are chemical properties of francium?
The chemistry of francium is not known; francium has properties similar to caesium.
What is different about francium and rubidium?
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.
Why isnt francium enough to make basic measurments?
Because francium was obtained only in very small samples, insufficient for the determination of physical properties.
What are the similarities of potassium and francium?
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
What are Francium's Chemical properties?
The chemistry of francium is practically unknown.
What are the properties of francium?
francium is commonly found as hard rock unless it comes from gravestones
Francium will bond with what other element?
The chemistry of francium is not experimentally known; it is only estimated. Francium should be have properties similar to caesium.
Does francium have any special properties?
yes
