Cl: This is the symbol for Chlorine, used in disinfectants and to purify water. Ar: This stands for Argon, a noble gas used in welding and lighting. K: This is the symbol for Potassium, vital for biological functions in plants ...
Chlorine is represented by the symbol Cl on the periodic table. It is a chemical element with atomic number 17 and is a greenish-yellow gas. Chlorine is widely used in various industries, such as water treatment, manufacturing of plastics, and production of disinfectants. Its symbol, Cl, is...
* Chlorine (symbol Cl) is a halogen. It is used as a disinfectant, especially in swimming pools. * Argon (symbol Ar) is a noble gas, making it almost entirely nonreactive. Incandescent lamps are often filled with noble gasses such as argon in order to preserve the filaments at high temp...
J.W. Döbereinerin 1817 showed that the combining weight, meaningatomic weight, ofstrontiumlies midway between those ofcalciumandbarium, and some years later he showed that other such “triads” exist (chlorine,bromine, andiodine[halogens] andlithium,sodium, andpotassium[alkali metals]). J.-...

(the electrons in the outermost shell). The first section of Mendeleev's book dealt with just eight of the known elements — carbon, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine and iodine — and those two strategies worked for those particular elements, according to Michael D. ...
Some snacks wouldn't taste the same without a compound containing the mystery element and chlorine (Cl), found in the same period, or row, on the periodic table. Your taste buds have specialized receptors that sense the mystery element. Name that element! The disappearing spoon; and other tr...
