Want this question answered?
Chlorine 35 is the most common it is mostly found In pools and in sometimes bleach. +++ That's not what was asked. It is used in bleach and disinfectant but in the compound calcium hypochlorite. The questioner asked "mostly found on Earth". It is not found in its elemental form in Nature because it is a very reactive, corrosive, toxic gas. Its main source on Earth is common salt (table~, rock~ or sea~), i.e. the compound Sodium Chloride.
Xenon is a trace gas in Earth's atmosphere, occurring at 0.087±0.001 parts per million, or approximately 1 part per 11.5 million.
* Fluorine is found on Earth at about 585 mg/kg (crust) 1.3 mg/liter (ocean) * Chlorine is found on Earth at about 145 mg/kg (crust) 19400 mg/liter (ocean) * Bromine is found on Earth at about 2.4 mg/kg (crust) 67.3 mg/liter (ocean) * Iodine is found on Earth at about 0.45 mg/kg (crust) 0.06 mg/liter (ocean) * Astatine is not found on Earth in appreciable quantities (it has no stable isotopes) Earth's crust is about 8.5 * 1020 kg Earth's ocean is about 1.4 * 1018 liters This make fluorine the most abundant halogen *on Earth*, with chlorine 30% as abundant by mass, and 16% as abundant in number of atoms. Fluorine only has one stable isotope, whereas chlorine has two. Otherwise the race would not be even that close.

What on earth are "artificial" and "natural" chemicals? For the purposes of answering your question I'll assume that you mean "not commonly found in nature" and "commonly found in nature" respectively.I'll also assume that by "chlorine" you mean "gaseous elemental chlorine".It's a bad start when I have to begin answering a question by making not just one but two assumptions, by the way; it indicates you didn't think the question through nearly as much as you should have. There may be no such thing as a stupid question (I personally am not convinced this is true), but there certainly are poor questions.We don't find chlorine gas around much on Earth, because it's too reactive and there aren't any natural processes that generate it in large quantities (oxygen gas would be rare for the same reason, except that there is a natural process that generates oxygen - photosynthesis). However, there are a few ways it can be generated in small quantities/low concentrations, so I'm a little hesitant to label it "artificial". It is, however, true that if you buy a cylinder of chlorine gas, it didn't come from a chlorine gas spring somewhere.

The most abundant halogen in Earth's crust is fluorine. The most abundant halogen on Earth's surface for example is chlorine.

Importance & Benefits of Chlorine 1. Chlorine is essential to human life. 2. Chlorine is the 10th most abundant element in the human body. 3. Chlorine is the 11th most abundant natural element on earth. 4. Chlorine has saved more lives than any other chemical produced 5. Chlorine disinfects 98 percent of the U.S. drinking water supply. 6. Chlorine is needed in the production of 85 percent of all pharmaceuticals. 7. Chlorine is required in the production of 96 percent of all crop protection chemicals. 8. Chlorine is involved in 45 percent of all commercial products. 9. Chlorine uses and compounds identified as posing unreasonable health risks should be scientifically sorted out, and steps taken to control the associated risk.
in your pool. lol
20 percent of the earth
Most of the chlorine on Earth exists as sodium chloride or common salt. It is the 21st most abundant element in the Earth's crust. Chlorine has two principal isotopes, 35Cl (75.78%) and 37Cl (24.22%).
Yes
i really dont know

The reason why its called mother earth is from the quote 'Mother Nature' and nature is near enough the whole earth.
Most of chlorine on earth has been here since the earth was formed. A tiny fraction is produced from impacts of argon atoms with cosmic ray protons.
