It's quite simple. It's just the Atomic Mass minus the atomic number. That's because the atomic number is simply the number of protons and the atomic mass is (almost exactly) the number of protons plus neutrons. Unfortunately there is a complication.
The problem is that a particular element can have more than one isotope.
Each isotope has the same number of protons, but different numbers of neutrons. This can make the atomic mass a messy number that's not a nice whole number.
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.

Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons
No. of neutrons=Atomic mass -Atomic No.=10-3=7 It has 7 neutrons.
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
No. of neutrons=Atomic mass - Atomic number
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.

If you mean to find the amount of neutrons in an atom, you take the atomic mass and subtract the atomic number (the number of protons). That gives you the average number of neutrons.

To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
