It ignites spontaneously in air and reacts explosively with water. It is found in minerals such as carnallite, lepidolite, and pollucite. * This is the scientific and technical definition for the element rubidium.
Usage Examples
- Noun:
- The physicist studied the spectral lines of atomic number 37.
- Atomic number 37 is more reactive than potassium but less reactive than cesium.
- Traces of atomic number 37 can be found in certain mineral springs.

- The experiment required a pure sample of the element with atomic number 37.
Variants and Related Words
- Rubidium (Rb): This is the common name for the element. "Atomic number 37" and "rubidium" refer to the same substance, with "rubidium" being the term used in most chemical and general contexts.
- Rubidium (atomic number 37) is used in some types of atomic clocks.
Synonyms
