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.
On Earth, almost totally as chloride anion-containing salts.
* 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.
Chlorine is a Halogen. Along with the rest of the elements in the group. Mostly ending with ine. Bromine and Fluorine for example.
Chlorine is not found in the nature in his elemental form.
Chlorine is extracted from the salts. The most common salt is used for making chlorine is sea water. The sea water mostly consists Sodium chloride.
Most Basalt is found mostly in oceanic plates of Earth.
Chlorine occurs commonly both in the Earth's crust and in seawater
Nitrogen
the earth's wieght ( 90 % )
On Earth, almost totally as chloride anion-containing salts.
Mostly in the tropical & subtropical regions of the earth

I think silica can be found mostly in the center of the earth ( the core).-s

peroxide and hydrogen.
No, it is an alkaline earth metal.
almost every were on earth
