1. Francium is the most reactive metal.
2. The estimated melting point is 30 oC.
- 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.
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
No. Chemical and physical properties are different.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Francium is radioactive and rubidium not. Also the electron configuration, atomic number, physical properties, hazards etc. are different.
The period 6 element with chemical properties most like sodium is francium. Francium is also an alkali metal like sodium and exhibits similar reactivity due to having one valence electron in its outer shell. However, francium is highly radioactive and unstable, making it difficult to study its chemical properties in depth.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Because francium was obtained only in very small samples, insufficient for the determination of physical properties.
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
