in coal
is it really found in coal?
No, rubidium is not found in household objects.
Today, most rubidium is produced as a byproduct of the lithium refinement process. Rubidium was originally found in 1861 when Robert Bunsen and Gustav Kirchhoff analyzed lepidolite.
Rubidium is a chemical element with the symbol Rb and atomic number 37. It is a soft, silvery-white metal that belongs to the alkali metal group of the periodic table. Rubidium is usually found in minerals like lepidolite and pollucite.
A rubidium atom is larger than a neutral atom because, when it loses an electron to become an ion, it loses an electron from the outermost shell, increasing the effective nuclear charge which attracts the remaining electrons closer to the nucleus, reducing the size of the ion compared to the atom.
Rb is found in the 5th period. It is in the s block.
Rubidium hypochlorite is the name for this chemical formula.

Rubidium, being a very reactive metal, occurs naturally only in ionic compounds. It can be found in trace amounts of a lot of silicates. The three that most commonly contain small amounts of rubidium are pollucite, leucite, and zinnwaldite.
The word equation for rubidium and chlorine is: rubidium + chlorine -> rubidium chloride.
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.
The nearest noble gas to rubidium is krypton. Rubidium, which has the atomic number 37, is located in group 1 of the periodic table, while krypton, with the atomic number 36, is found in group 18. Krypton is one period above rubidium, making it the closest noble gas in terms of atomic number.
