18.5 neutrons
Neutrons can not be a fraction. Must be a whole number.
Chlorine has 18 neutrons
Chlorine has 2 stable isotopes present in nature, 35Cl and 37Cl with 18 and 20 neutrons respectively.
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.
If you mean how many electrons are required for an atom of chlorine to have no charge, the answer is 17 as chlorine has an atomic of 17 so therefore has 17 protons. These protons have a positive charge so it requires 17 negatively charged electrons in order to "balance" the atom.
Chlorine atom has 17 protons and 17 electrons. The number of neutrons depends on the isotope considered. Chlorine has four isotopes: Cl-35, Cl-36, Cl-37 and Cl-38 with 18, 19, 20 and 21 neutrons respectively. However out of these, Cl-35 and Cl-37 are the most stable isotopes.
A neutral nitrogen atom has 7 protons and 7 neutrons in its nucleus and 7 electrons in orbitals around the nucleus.
How many protrons and neutrons does silicon have in the nucleus?
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.
There are 77 Neutrons in the nucleus of one atom of Xenon

Helium has two neutrons and two protons in its nucleus.
20
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.
Chlorine has an Atom number of 17 and atom mass of 35.45. So atom mass - atom number gives you 18.45
