The most abundant isotope of arsenic is arsenic-75.
These are the Hydrogen isotopes with the least mass: Hydrogen 1-protium Hydrogen 2-deuterium Hydrogen 3-tritium
It means that the atom being discussed is an isotope of iron that has a mass number of 57, which means that the atom has 31 neutrons.Added:It is the 3rd most abundant Fe isotope after Fe-56 and -54.
Fermium is an extremely rare artificial isotope.
The number of neutrons in an iron atom can vary depending on the isotope of iron. For the most common isotope, iron-56, there are 30 neutrons.
In the most abundant isotope of iron, there are 26 protons and 26 neutrons.
The most abundant isotope of arsenic is arsenic-75.
Tritium is the most abundant hydrogen isotope

An isotope of cobalt is used to to kill cancer cells. The isotope americium-241 is used in smoke detectors.
Iron 56 is the lightest
Fermium is an extremely rare artificial isotope.
The number of neutrons in an iron atom can vary depending on the isotope of iron. For the most common isotope, iron-56, there are 30 neutrons.
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.
Potassium I reckon
Boron-11 is the most abundant isotope of boron in nature because it is a stable isotope with a relatively long half-life, making it less likely to decay into other isotopes. Boron-10, another naturally occurring isotope, is less abundant because it is less stable and undergoes neutron capture to form boron-11.
