Take the Atomic Mass and round it to the nearest whole number. Then subtract this number and the atomic number of that element.
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.

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.
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
The number of neutrons in an atom can affect the atomic mass of an atom.
Mass number!:)
The number of neutrons in an atom is called the neutron number.
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
The total amount of protons and neutrons in an atom is its mass number.
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
The mass number is the sum of protons + neutrons.
Of course, number of neutrons or neutron number !
