20
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.
18
One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
Chlorine has an Atom number of 17 and atom mass of 35.45. So atom mass - atom number gives you 18.45
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.
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.
There are two main isotopes of chlorine. Every chlorine atom has 17 electrons where there are 18 and 20 neutrons in chlorine-35 and chlorine-37 respectively.
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.
Presumably you mean how many neutrons? Chlorine has various isotopes, each having a different number of neutrons - take the mass of the isotope, subtract the atomic number (17), and the answer is the number of neutrons.
17 electrons. The number of protons and electrons is always the same.
If you mean the element Vanadium, there are 28 neutrons.
