Neutron is the difference btw the atomic no and the mass no of an element.
The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n
Number of neutrons = Atomic mass of an isotope - Number of protons (Atomic number)
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
For each isotope of Md the number of neutrons is different.Number of neutrons = Mass number of a Md isotope -101
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Each isotope of beryllium has a different number of neutrons.
It depends on what isotope you're talking about. To find the number of neutrons in a particular isotope, take the atomic mass and subtract the atomic number. For example, Na has a mass of roughly 23amu and 11 protons, so an Na-23 atom would have 12 neutrons.
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope – atomic number
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an Fm isotope - 100
