Each isotope of an element has a specific number of neutrons (number of neutrons = atomic weight - atomic number).
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.

Carbon's got an atomic number of 6. That means it has six protons. Carbon-14 means the atomic mass is 14. Atomic mass is Neutrons+Protons. 14-6=8
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
Most atoms of Barium (Ba) have 81 neutrons, but some very rare isotopes have more. The average number of neutrons an atom of Barium has is 81.327, which is its atomic weight (minus the protons).
There are 19 known isotopes of americium, with neutron counts ranging from 136 to 154. Americium-241, the easiest to produce, has 146 neutrons. Number of neutrons = Atomic weight (rounded) of an americium isotope - 95 Each isotope has a different number of neutrons. Americium has also 95 protons and electrons.
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
An average helium atom typically contains two neutrons. Helium has an atomic number of 2, meaning it has two protons in its nucleus. The most common isotope of helium, helium-4, has two protons and two neutrons, resulting in its overall atomic mass of four.
An atomic nucleus contain protons, neutrons and electrons - not oxygen.
