What is the physical state of francium?
Francium is a highly radioactive alkali metal that is a solid at room temperature. Due to its extreme rarity and radioactivity, it is difficult to observe in its solid state. Francium readily reacts with air and moisture, leading to its rapid decay.
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 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.
How was francium named francium?
Francium was named after France, the country it was dicovered in.
What is the numerical value of francium?
The atomic number of francium is 87.
Is francium rough or smooth?
It is impossible to know these characteristics.
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.
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.
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 is the physical state of francium?
Francium is a highly radioactive alkali metal that is a solid at room temperature. Due to its extreme rarity and radioactivity, it is difficult to observe in its solid state. Francium readily reacts with air and moisture, leading to its rapid decay.
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.
Does a point have no physical characteristics?
No, a point does not have physical characteristics.
Do zebras have physical characteristics?
