What is the physical state and appearance of francium?
Francium is a highly radioactive and rare alkali metal. It is a solid at room temperature, but due to its extreme radioactivity, it is typically stored in mineral oil to prevent reaction with moisture in the air. Francium also has a silvery-white appearance when freshly cut.
What is the physical state of francium at room temperature?
Francium is a highly radioactive element with a very short half-life, so it is not commonly found in nature. Its melting point is just slightly above room temperature, so at room temperature, it would likely be in a solid state. However, due to its extreme rarity and radioactivity, francium is typically produced in very small quantities in laboratory settings for research purposes.
What is the state of francium at 20 degrees celsius?
Francium is a highly unstable and radioactive element, so its natural occurrence is extremely rare and limited. Due to its short half-life, it is difficult to determine the state of francium at specific temperatures. However, as a metal, it is generally assumed to be solid at 20 degrees Celsius.
What is the formula of the most stable oxygen of francium?
The most stable oxidation state of francium is +1. Francium readily loses its single valence electron to attain a stable electron configuration similar to the noble gas configuration of cesium.
What is the element with the lowest oxidation state on the periodic table?
The element with the lowest oxidation state on the periodic table is Francium.
What would be the physical state of francium be at 50 degrees Celsius?
At 50 degrees Celsius, francium would be in a solid state. Francium is a metal that has a melting point of 27 degrees Celsius. At temperatures lower than its melting point, francium would exist as a solid.
What is the francium normal state?
Francium is a solid.
What is francium normal state?
At room temperature francium is a solid.
What does francium look like in its normal state?
The appearance of francium is not known.
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 is different about francium and rubidium?
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.
Does francium gain or lose electrons and what state how many?
Francium lose one electron to form the cation Fr+.
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.
