A chlorine atom has 17 electrons, which means that its electronic configuration would be (2,8,7). For it to become an ion, it would have to get another electron for the valence shell to be full. Therefore a chloride ion would have 17+1=18 electrons in total. Electronic configuration = (2,8,8)
I hope i'm right. I just learnt this :3
It depends on which atom of chlorine. Chlorine mainly exists as 2 different atoms. One with a mass number of 35 and another with a mass of 37 (these different atoms are called isotopes) The atomic number of chlorine is 17 so in order to work out the number of neutrons you have to subtract the atomic number from the mass number. In the case of the atom with a mass of 35, it would have 35-17 = 18 neutrons. In the case of the atom with a mass of 37, it would have 37-17 = 20 neutrons.
There should be 17, since the atomic number is how many protons (of which there are the same amount of neutrons). However, if it is an unstable isotope, it would have more neutrons.
Chlorine 35 and chlorine 37 have a different number of neutrons. Chlorine 35 has 18 neutrons, while chlorine 37 has 20 neutrons. This causes them to have different atomic masses.
Chlorine typically has 18 neutrons in its nucleus, which accounts for its atomic weight of 35.45 g/mol.

The main difference between chlorine-35 and chlorine-37 is their atomic mass. Chlorine-35 has an atomic mass of 35 amu, while chlorine-37 has an atomic mass of 37 amu. This is due to the different number of neutrons in their nuclei: chlorine-35 has 18 neutrons, while chlorine-37 has 20 neutrons.
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.
the average amount of neutrons in chlorine is 18, but there could be more or less with the different isotopes
Chlorine has 18 neutrons.
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
There should be 17, since the atomic number is how many protons (of which there are the same amount of neutrons). However, if it is an unstable isotope, it would have more neutrons.
It depends on which isotope of chlorine you're interested in.
Chlorine exist as two isotopes(same number of electrons and protons but different number of neutrons), although there are traces of one more but we're not to sure. ~70% of Chlorine is Chlorine-35 which contains 17 electrons and 18 neutrons ~30% of Chlorine is Chlorine-37 which contains 17 electrons and 20 neutrons and ≤1% of Chlorine-36........
Chlorine 35 and chlorine 37 have a different number of neutrons. Chlorine 35 has 18 neutrons, while chlorine 37 has 20 neutrons. This causes them to have different atomic masses.
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.

Chlorine has 17 protons and 18 neutrons, while sodium has 11 protons and 12 neutrons.
