What is francium on the periodic table?
Francium, number 87, was the last of these elements to be discovered in nature. From its position in the table, it was clear that element 87 would be a reactive alkali metal, the heaviest member of the family lithium, sodium, potassium, rubidium and caesium.

Where is francium on periodic table?
francium (Fr), heaviest chemical element of Group 1 (Ia) in the periodic table, the alkali metal group. It exists only in short-lived radioactive forms.
What is the symbol and used for element francium in periodic table?
symbol Fr
Francium is a chemical element with symbol Fr and atomic number 87. Classified as an alkali metal, Francium is a solid at room temperature.
Where is caesium on the periodic table?
This means the element for which it is easiest to remove an electron and form a cation, is in the bottom left-hand corner of the periodic table, where caesium is found.

Where is rubidium on the periodic table?
So there we have rubidium, the explosive red element number 37 in the periodic table.
Why is rubidium named rubidium?
Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after the two prominent red lines of its spectrum.
What does the element francium look like?
For appearance, francium is presumed to have a silvery, and gray color to it. No one knows the precise scent to it because it is very rare and usually found in uranium. The texture is metallic and also, it is presumed to be like that.
Is the element francium a liquid element or solid?
Francium is the shiny metal in its pure state and exist in liquid form at room temperature rather than a solid. Francium belongs to alkali group of the periodic table so its physical properties are similar with alkali group elements.
What elements does francium combine with?
Francium will certainly react in the air. It reacts with nitrogen, oxygen water and carbon dioxide (which together compose more than 99% of the air).
Why is francium a radioactive element?
This is due to the distance of its electrons from the nucleus and its atomic number . What is more, francium is the rarest element that occurs in nature but one. The most rarely occurring one is astatine. This element is extremely radioactive and decays into radon, radium, and astatine.
