We elaborate the uses of chlorine and atomic properties with characteristics. Chlorine is a greenish-yellow chemical element with an atomic number 17. Its symbol is Cl and it belongs to the group of halogens and its usual state in nature is gaseous. Chlorine is located at position 17 on the periodic table.
On this page you can discover the chemical properties of chlorine and information about chlorine and other elements on the periodic table such as fluorine, bromine, sulfur or argon. You will also learn what chlorine is for and learn about its uses through its properties associated with chlorine such as its atomic number or the usual state in which chlorine can be found.
You will see qualities of chlorine such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in chlorine atoms and other properties.
For some elements, some of this information is unknown. In these cases we show the properties attributed to them.
Elements from the halogen group such as chlorine are presented as chemically active diatomic molecules. The name halogen comes from the Greek and its meaning is “salt forming”. They are halogen elements among which is chlorine, they are oxidants. Many synthetic organic compounds, and some natural organic compounds, contain halogen elements such as chlorine. These types of compounds are known as halogenated compounds.
The state of chlorine in its natural form is gaseous (non-magnetic). Chlorine is a greenish-yellow chemical element and belongs to the group of halogens. The atomic number for chlorine is 17. The chemical symbol for chlorine is Cl. The melting point of chlorine is 171.6 degrees Kelvin or -100.55 degrees Celsius or degrees Celsius. The boiling point of chlorine is 239.11 Kelvin or -33.04 degrees Celsius or degrees Celsius.
Uses of chlorine
Some chlorine-containing molecules have been responsible for ozone depletion. If you’ve ever wondered what chlorine is for , here is a list of its possible uses:
- Chlorine is used (usually a certain chlorine compound) to kill bacteria in swimming pools and drinking water. It is also used in disinfectants and bleaches for the same reason. Chlorine is very effective against the E. coli bacteria.
- While it is not used as often today, some military still uses chlorine as a poisonous gas. It is most commonly used in this way by terrorist groups.
- Chlorine is used to make plastics.
- PVC (polyvinyl chloride) is made from chlorine. PVC is used to make clothes, floors, electrical cables, flexible tubes and pipes, figures (statues), water beds and inflatable structures. PVC is also currently used to make roof tiles.
- Chlorine is used in the extraction of bromine .
- Methyl chloride, another important chlorine compound, is used as an anesthetic. It is also used to make certain silicone polymers and is used to extract fats, oils, and resins.
- Chloroform, which contains chlorine, is used as a common solvent in science laboratories. It is also used to kill worms in animal wounds.
- Trichlorethylene is used to degrease metal parts.
Atomic properties of chlorine
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find chlorine within the periodic table of the elements, chlorine is in group 17 and period 3. Chlorine has an atomic mass of 35,453 u.
The electronic configuration for chlorine is [Ne] 3s2 3p5. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The average radius for chlorine is 100 pm, its atomic radius or Bohr radius is 79 pm, its covalent radius is 99 pm, and its Van der Waals radius is 175 pm. Chlorine has a total of 17 electrons whose distribution is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons and in its third layer it has 7 electrons.
