18
The number of neutrons is different for each isotope. Chlorine-35 has eighteen neutrons. Chlorine-36 has nineteen neutrons. Chlorine-37 has twenty neutrons. ....... etc.
A Chlorine atom typically has 18 neutrons in its nucleus. This is because the atomic number of Chlorine is 17, which represents the number of protons in its nucleus. By adding the number of protons to the number of neutrons, we can determine the total number of particles in the nucleus.
There are 17 protons in the nucleus of an atom of chlorine.
There are 77 Neutrons in the nucleus of one atom of Xenon
A Xenon neutron has between 70 to 82 neutrons.
In any substance whatever, each atom has only one nucleus.
Helium has two neutrons and two protons in its nucleus.

30 neutrons in the most stable isotope of iron (Fe-56).
Each chlorine atom contains 17 electrons, which offset the electric charge of the 17 protons in the nucleus of each atom, as indicated by the fact that the atomic number of chlorine is 17. The number of neutrons per atom varies, however, depending on which isotope of chlorine is examined. There are two naturally occurring and radioactively stable isotopes of chlorine, with mass numbers of 35 and 37, and there are many other radioactive isotopes. The number of neutrons in an atom of a particular isotope may be found by subtracting 17, the atomic number of chlorine, from the mass number.
An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.
