Only in chemical laboratories or small scale units for rubidium production.
Pure rubidium is obtained after a very long process of repeated fractional ceystallizations.
Yes, rubidium is a pure element found in nature. It is an alkali metal and is the 16th most abundant element in the Earth's crust. Rubidium is most commonly obtained as a byproduct of lithium production or extracted from certain minerals.
Pure rubidium wouldn't be something to taste - it's explosively reactive with, well, just about everything. However, rubidium when it is in a compound with a halogen (like chlorine, or fluorine) makes a salt, and it will taste salty/bitter and appear like a white granular solid (like table salt.)
Rubidium hypochlorite is the name for this chemical formula.
Rb is the symbol for the element, rubidium.
Rb is rubidium, O is oxygen. They will combine to form Rb2O which is called rubidium oxide.
Rubidium is an element and so it is made of nothing but rubidium.
Rubidium iodide
Rubidium is not flammable.
Rubidium is a neutral atom in its elemental form. The rubidium ion, found in rubidium compounds, is smaller than a neutral rubidium atom.
Rubidium's symbol is Rb.
