__ ﻿ Where is it found and what form is it in...__

 This Information was copy and pasted from this great website [] As noted above, elemental chlorine is not found in nature. Rather, chlorine is found mainly in the form of the chloride ion, a component of [|salts] deposited in the [|earth] or dissolved in the [|oceans]. About 1.9 percent of the mass of seawater is chloride ions. Higher concentrations of chloride are found in the [|Dead Sea] and in underground brine deposits. Given that most chloride salts are soluble in [|water], the abundance of chloride-containing minerals is higher in regions with dry climates and deep underground, where the salts seldom come in contact with water. Common chloride minerals include //halite// ([|sodium chloride]), //sylvite// (potassium chloride), and //carnallite// (potassium magnesium chloride hexahydrate).

__Physical Facts of Chlorine...__ Chlorine's Atomic number is 17 **2.** Chlorine's melting point is -100.98Â°C **3.** Chlorine's boiling point is 34.6Â°C **4.** Chlorine was first discovered by Carl Wilhelm Scheele in Sweden back in 1774 **5.** Chlorine is a member of the halogen group and combines with nearly all the other elements. **6.** Both in gas form as well as in liquid, Chlorine is an irritant and will negatively affect the respiratory system in gas form while it can burn your skin when in liquid form. **7.** More than a few breaths of Chlorine in concentrations of 1000ppm will typically kill you. **8.** Chlorine in gas form is a yellow-greenish color. **9.** Chlorine containing molecules in the upper atmosphere have been implicated in destruction of our ozone layer. **10.** Sodium Chloride, otherwise known as rock schalt, is the most common compound containing Chlorine and has been around and in use [|dating] back to 3000 B.C.

__ Melting Point and Boiling Point __

Chlorine Melting point is 172 Kelvin (which is also its freezing point) Chlorine's boiling point is 239 Kelvin (which is also its condensing point) For reference, water freezes at 273 Kelvin and boils at 373 Kelvin. This means that chlorine will remain a gas until quite cold temperature of about negative 34 degrees centigrade

__**How Chlorine is useful...**__

Chlorine has a variety of uses. It is used to disinfect water and is part of the sanitation process for sewage and industrial waste. During the production of paper and cloth, chlorine is used as a bleaching agent. It is also used in cleaning products, including household bleach which is chlorine dissolved in water. Chlorine is used in the preparation of chlorides, chlorinated solvents, pesticides, polymers, synthetic rubbers, and refrigerants.

__**How can chlorine harm people**__

Given the ubiquity and volume of chlorine in industrial and commercial locations, widespread exposures could occur from an accidental spill or release, or from a deliberate terrorist attack. Because chlorine is a gas at room temperature, exposure occurs via inhalation. People may also be exposed to chlorine through skin or eye contact, or through ingestion of chlorine-contaminated food or water. This Information was copy and pasted from this great website []

what is the ABUNDANCE IN THE EARTHS CRUST for chlorine

Abundance earth's crust: 145 parts per million by weight What per million by weight mean... ppm in this context probably means parts per million. This is the concentration of a chemical or element in something like food or drink. for example 8 milligrams of [|mercury] in 100 grams of fish would result in a mercury concentration of 0.8 ppm (parts per million) Parts per million ppm parts per million
