You find out the charge of nucleus (a number of protons), multiply it by mass of proton. Then substitute the result from the mass of nucleus and divide by mass of neutron. The result will give number of neutrons in the nuclei.

∙ 14y agoYou find out the Atomic Mass and atomic number and simply use the equation:
atomic mass - atomic number = number of neutrons there are
e.g. Aluminum has an atomic mass of 27 and and atomic number of 13, so it has 14 neutrons, simple

How many protons and neutrons are in an atom of 50V?
how many protons an d neutrons are in vanadium
How many number neutrons magnesium?
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
How many nuetrons in a sodium atom?
there are 11.99 neutrons in an atom of sodium
How do you figure out how many neutrons are found in an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How many neutrons are in an atom I?
A typical atom of iodine contains 74 neutrons.
How many neutrons does an atom of 21Ne have?
11 neutrons
How many neutrons in a selenium atom?
45 neutrons
What accounts for most of the size of an atom?
It depends it can be protons of neutrons depending on which atom but for many it is neutrons
How do you calculate how many neutrons there are in a atom?
The atomic weight minus the number of protons = the atom's neutrons.
How many neutrons are found in one atom of rm 36Cl?
There are 19 neutrons in a 36Cl atom.
How many neutrons are in the center of a atom of niobium?
52 neutrons.
How many neutrons does a stable atom of Zn have?
35 neutrons
How many neutrons are in an atom of I?
A typical atom of iodine contains 74 neutrons.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
How can you figure the numbers of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
