Number of neutrons = Mass number of an isotope - 93The most common isotope has 144 neutrons.
Boron has 5 neutrons and 5 protons for its most common isotope
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Pm isotope - 61
For each Es isotope the number of neutrons is different.Number of neutrons = Mass number of an Es isotope - 99
146 neutrons.
The amount of neutrons can always be found by taking the atomic number from the mass number. Uranium has 146 neutrons. It depends on the isotope. See the link below for a list of uranium isotopes and how many neutrons are in each. You cannot tell how many neutrons it has with the given information. The most abundant isotope happens to be 238U, which has 146 neutrons.
it depends on the element and isotope
Which isotope of which element? The answer depends entirely on those details.
The most stable isotope of Argon has 22 neutrons (Ar40)
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
In the most common isotope of silicon, there are 14 neutrons.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
