What is the chemical symbol of antimony?
Antimony's most abundant isotope is notated 12251Sb.
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.

Which is the most abundant isotope for hydrogen?
Tritium is the most abundant hydrogen isotope
What is the most abundant isotope for arsenic?
Arsenic has only one stable isotope 75As
What is the number of subatomic particles for antimony?
Antimony has 51 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an antimony isotope = Mass number - 51
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 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.
What element which has the most abundant isotope which has 20 neutrons?
Potassium I reckon
How many neutrons does antimony contain?
Antimony (symbol Sb) has three isotopes: 121Sb, 123Sb, and 125Sb. The 121 isotope has 70 neutrons, and the 123 isotope has 72 neutrons. The 125 isotope isn't stable and will decay, but it has 74 neutrons.
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).
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.
