∙ 13y agoThis has to due with the abundance of each. Lets break it down for a moment.
The mass number is the sum of the number of protons and the number of neutrons. All chlorine atoms have 17 protons, so if we so a little subtraction, we can find out that there are 18 neutrons in 35Cl (Chlorine-35) and 19 neutrons in 37Cl. Another important piece of information that we need to know is that the atomic mass is an average of its isotopes. So lets say that there are equal amounts of 35Cl and 37Cl (50% of each). If we calculated the atomic mass (the average of the two), we would get a number that's directly in-between 35 and 37 since they are found in equal amounts in nature. Then the atomic mass would be 36.
But we know this isn't true. There are not equal amounts of each isotope in nature; therefore, the atomic mass will not fall directly between the two masses of isotopes. The atomic mass of chlorine is 35.45, which means one isotope is more abundant than the other. Since 35.45 is closer to the weight of 35Cl, we know there is more of that isotope than 37Cl. Then, because we already figured out that there are 18 neutrons in 35Cl, we can officially say that most chlorine atoms have 18 neutrons.

∙ 14y agoSince the average Atomic Mass of chlorine is closer to 35 than 37, it indicates that there are more chlorine-35 isotopes present in nature. Since the atomic number of chlorine is 17, which represents the number of protons in the nucleus, it follows that most chlorine atoms contain 18 neutrons (35-17 = 18) to give an average atomic mass close to 35.45 u.

∙ 13y agoMost chlorine atoms contain 18 neutrons because:
The atomic number of Chlorine is 17 - indicating the number of protons found in the atomic nucleus. Seeing as the atomic mass is 35, we subtract the number of protons from 35 to get the number of neutrons, 18.
We test our equation: 17 protons + 18 neutrons = 35
Chlorine-35 is the most common natural occurring isotope of chlorine which is why most chlorine atoms contain 18 neutrons.

∙ 15y agoThe atomic number of chlorine is 17 Both isotopes therefore have 17 protons and 17 electrons Cl 35 has 18 neutrons while Cl 37 must have 20 neutrons

∙ 14y agoThe Cl-35 isotope is more abundant, because the average atomic mass is closer numerically to 35 than to 37.

∙ 13y agoYes, it does.
No, the atomic mass of chlorine on the periodic table is actually an average of all the naturally occurring isotopes of chlorine, taking into account their relative abundance. The most common isotope of chlorine is chlorine-35, but there is also a small percentage of chlorine-37, which contributes to the overall atomic mass.
Chlorine-35 isotope has a higher abundance than Chlorine-37. Chlorine-35 makes up about 75.77% of naturally occurring chlorine atoms, while Chlorine-37 makes up about 24.23%.
There isn't an existing compound as calcium chlorine, therefore it cannot be compared with calcium chloride which is a naturally occuring salt.
Chlorine is a naturally occurring gas at the room temperature and atmospheric pressure which is a non metal.
Which of the following does not occur naturally as a diatomic molecule? Chlorine, Hyrdogen, nitrogen or sulfur?
Chlorine is a non metal element. Atomic mass of it is 35.
The electron structure of the two isotopes is the same. They differ in the number of neutrons in the nucleus 37Cl has two more than 35Cl. These then means that 37Cl is more radioactive that 35Cl
Chlorine is a naturally occurring chemical element, but most of the chlorine used in industry is produced through electrolysis of salt water or other chlorine-containing compounds.
Chlorine naturally occurs in the Earth's crust, oceans, and soil. It is also found in various types of rocks and minerals. Additionally, chlorine gas can be released from volcanic eruptions and sea spray.

yes
Chlorine is not typically found in significant levels in groundwater naturally. It is often detected as a result of human activities such as disinfection or industrial processes. During testing, any chlorine detected is more likely to be from added disinfectants rather than occurring naturally.
Chlorine-35 isotope has a higher abundance than Chlorine-37. Chlorine-35 makes up about 75.77% of naturally occurring chlorine atoms, while Chlorine-37 makes up about 24.23%.
No, chlorine does not naturally convert into bromide. These are two different chemical elements and do not undergo spontaneous conversion from one to the other.
Oxygen does not naturally contain chlorine in its pure form. Chlorine is a separate element on the periodic table and does not make up any part of oxygen's atomic structure.
Chlorine can be separated from water by allowing the water to sit for a period of time, as chlorine will naturally evaporate. Alternatively, chlorine can be removed by using activated carbon filters or chemical treatment methods such as sodium metabisulfite.
Chlorine is a gas at room temperature and pressure. It is found naturally in the Earth's crust and in seawater.
