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.

The number of neutrons in an atom of chlorine can vary depending on the isotope. The most common isotope of chlorine, chlorine-35, contains 18 neutrons. However, there is also an isotope of chlorine, chlorine-37, which contains 20 neutrons.

This depends because chlorine exists as different isotopes. The two principal stable isotopes are chlorine-35, 35Cl (75.78%) and chlorine-37, 37Cl (24.22%). An atom of 35Cl would have 18 neutrons while 37Cl would have 20 neutrons.

Neutrons = 18. Protons = 17 to figure out the # of neutrons to the mass-protons which is 18
A chlorine atom in ground state has 17 electrons. (17 protons, 18 neutrons)

How many neutrons and electrons in chlorine?

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.


How many neutrons are in the nucleus of a Chlorine atom?

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.


Does an atom of chlorine have 17 protons and 18 neutrons?

No, an atom of chlorine typically has 17 protons and 18 neutrons. This configuration gives it a mass number of 35.


How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?

A chlorine atom with 17 protons will also have 17 electrons to maintain neutrality. The number of neutrons (18) does not affect the number of electrons in an atom.


How many neutrons and electrons are in the element chlorine?

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.


How many neutrons are found in one atom of rm 36Cl?

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).
