Can't tell because it is NOT true
Carbon-12 is the most abundant isotope of carbon, making up about 98.9% of carbon found in nature. Carbon-13 is the second most abundant isotope, making up about 1.1% of natural carbon.
Tritium is the most abundant hydrogen isotope
To determine the most abundant isotope in a sample, scientists use a technique called mass spectrometry. This method measures the mass-to-charge ratio of isotopes in the sample, allowing researchers to identify the isotope that appears in the highest abundance.
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
The sum of elements like fluorine can be found by adding the atomic masses of its isotopes, weighted by their abundance in nature. The most abundant isotope of fluorine is fluorine-19, which has an atomic mass of 18.998403163 u. By accounting for the abundance of this isotope in nature, the average atomic mass of fluorine can be calculated, which is approximately 18.998 u.
Carbon-12 is the most abundant isotope of carbon, making up about 98.9% of carbon found in nature. Carbon-13 is the second most abundant isotope, making up about 1.1% of natural carbon.
The most abundant isotope of arsenic is arsenic-75.
Tritium is the most abundant hydrogen isotope
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.
An isotope of cobalt is used to to kill cancer cells. The isotope americium-241 is used in smoke detectors.
Potassium I reckon
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).
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.
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
To determine the most abundant isotope in a sample, scientists use a technique called mass spectrometry. This method measures the mass-to-charge ratio of isotopes in the sample, allowing researchers to identify the isotope that appears in the highest abundance.
Antimony-121 at 57.25%, the rest is Antimony-123
The most abundant isotope has 7 each.
