We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
You would subtract the atomic number from the mass number.
mass #-atomic#=# of neutrons
Find out how many protons (atomic number) and what the mass number of a particular element is. Then subtract the number of protons from the rounded mass number to get the number of neutrons in a particular atom.
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
subtract. mass number - atomic number = number of electrons.
You would subtract the atomic number from the mass number.

Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
If you subtract the mass number by the atomic number you get the number of neutrons.
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.

To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
