Rubidium is the twenty-third most abundant element in the Earth's crust. It occurs in the minerals pollucite, carnallite, leucite and lepidolite, from which it is recovered commercially. Potassium minerals and brines also contain this element and are a further commercial source.

What is the most abundant isotope for arsenic?
Arsenic has only one stable isotope 75As
What is the most abundant isotope of oxygen?
There is only one abundant isotope of fluorine and that is 19FFluorine-19 is the most common isotope, its abundance is classed as 100% because no other Fluorine isotopes exist in significant quantities. It is also the only stable Fluorine isotope.
What element which has the most abundant isotope which has 20 neutrons?
Potassium I reckon
Are all elements are composed of atoms that cannot be divided?
No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.
What is the mass number of the most common isotope of carbon?
As the atomic number of nitrogen is 7, the most abundant isotope of this atmospheric gas must have 7 neutrons (14.007 - 7 = about 7), and this will make nitrogen-14 that isotope that is most abundant.
Which is the most abundant isotope for hydrogen?
Tritium is the most abundant hydrogen isotope
What is the number of neutrons in an atom of the most common isotope of rubidium?
69
What is the atomic waste of rubidium?
The isotope rubidium-85 is a secondary fission product, from the decay of krypton-85. Also the isotope rubidium-87 is a fission product.
What is the most abundant isotope for arsenic?
Arsenic has only one stable isotope 75As
What is the number of subatomic particles in rubidium?
Rubidium has 37 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a rubidium isotope = Mass number - 37
What is the most abundant isotope of oxygen?
There is only one abundant isotope of fluorine and that is 19FFluorine-19 is the most common isotope, its abundance is classed as 100% because no other Fluorine isotopes exist in significant quantities. It is also the only stable Fluorine isotope.
Which isotope occurs in greater abundance in chlorine?
Chlorine-35 is the most abundant isotope of chlorine.
What is Number of subatomic particles of rubidium?
Rubidium has 37 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a rubidium isotope = Mass number - 37
What element which has the most abundant isotope which has 20 neutrons?
Potassium I reckon
What is the most abundant radioactive isotope?
An isotope of cobalt is used to to kill cancer cells. The isotope americium-241 is used in smoke detectors.
Are all elements are composed of atoms that cannot be divided?
No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.
What is francium's most abundant isotope?
Francium has no stable isotopes. That means it doesn't really have a "most abundant" isotope; they're all pretty much nonexistent. There are trace amounts of 223Fr in uranium minerals, because it's a decay product of 227Ac (which is itself a decay product in the decay chain of uranium).
