No, it is too reactive to occur as a pure element in nature.
Rubedium is not anything I know, but you probably meant rubidium, which is indeed a metal.
Fluorine is never found in nature as a pure native element due to its high reactivity. It typically forms compounds with other elements such as in minerals like fluorite.
Rubidium (Rb) occurs naturally in minerals such as Pollucite, Carnallite and Lepidolite.
It is found in nature in its pure form (not as a compound).
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.
