Uses of Chlorine

What is Chlorine?

Chlorine takes on the appearance of pale yellow-green gas. Chlorine in liquid form can burn the skin, and chlorine in gaseous form irritates the mucous membrane....

Structure of Chlorine

Chlorine has an atomic number of 17. This means that chlorine’s atomic structure has a total of 17 protons and 17 electrons. These electrons are organized into three electron shells: K, L, and M. Chlorine has two electrons in its first electron shell and eight electrons in its second electron shell. Finally, the chlorine atom’s outermost electron shell (also known as the valence shell) has a total of 7 electrons....

Physical and Chemical Properties of Chlorine

Chlorine is a gas and has a greenish-yellow appearance at room temperature and atmospheric pressure. Chlorine is the second halogen element of Group 17 (Halogen Group) of p-block elements with- Atomic Number (Z) or molar mass of Chlorine: 17 Atomic Mass of Chlorine: 35.45 Boiling Point of Chlorine: 239.11 K Melting Point of Chlorine: 171.6 K Density of Chlorine: 1.5625 g/cm3 Electronegativity of Chlorine: 3.16 Valency of Chlorine: 1 Chemical Formula or Symbol of Chlorine: Cl Chlorine is 2.5 times heavier than air. Chlorine is a highly electronegative and electron affinity element. When charcoal is present, the reaction between Chlorine and Hydrogen occurs quickly in the dark.  Because of its strong affinity for Hydrogen, Chlorine can react with a wide variety of molecules. For example, when Chlorine combines with hydrocarbons, chlorine atoms gradually replace the hydrogen atoms. However, chlorine atoms are easily added to the double or triple bond if the hydrocarbon is unsaturated. Each Chlorine molecule contains two atoms (Cl2). Except for the lighter noble gases, practically all elements interact with chlorine to form Chlorides.  The Chlorides of most metals are ionic crystals, but those of semimetals and nonmetals are primarily molecules....

Isotopes of Chlorine

The element Chlorine (Cl) has a total of 25 isotopes ranging from 28Cl to 52Cl. Out of these 25 isotopes, only two isotopes are stable. The stable isotopes of Chlorine are 35Cl with 75.77% of abundance and 37Cl which is 24.23% abundant, thus giving chlorine a standard atomic weight of 35.45. The radioactive isotope that lived longest is 36Cl, which has a half-life of 3.01 × 105 years....
