Chlorine
Question 1: Is Chlorine a metal or a non-metal?
Answer:
Yes, Chlorine is a metal, it is a yellowish-green gas with a high degree of reactivity. Chlorine reacts with various metals to form a wide range of compounds.
Question 2: Write the electron dot structure for Potassium Chloride.
Answer:
Since, the number of valence electrons in Potassium (K) and Chlorine (Cl) are 1 and 7, respectively.
Hence, the electron dot structure for Potassium Chloride is below:
Question 3: What happens when Lime Water reacts with Chlorine?
Answer:
Lime water reacts with chlorine to give Calcium hypochlorite (CaOCl2) or Bleaching Powder as shown in the chemical reaction below:
Question 4: Why Bleaching powder gives the smell of Chlorine?
Answer:
Bleaching powder gives the smell of chlorine because it reacts with the Carbon dioxide present in nature to give Calcium carbonate and Chlorine, as shown in the reaction below:
Question 5: Why is chlorine gas Green?
Answer:
Chlorine is a yellow-green gas at room temperature. Chlorine has a strong, unpleasant, bleach-like odour that can be perceived even at low concentrations. Because the chlorine gas concentration is approximately 2.5 times that of air, it will initially remain close to the ground in locations with low air movement.
Question 6: Is chlorine a poisonous gas?
Answer:
Gaseous chlorine is toxic and is classified as a lung irritant. It has an intermediate water solubility and the ability to produce acute harm to the upper and lower respiratory tracts. Chlorine gas is immediately detectable due to its strong odour.
Question 7: What is chlorination?
Answer:
Chlorination is a typical chemical treatment used to destroy bacteria in water.
Question 8: What is the valency of chlorine?
Answer:
In its atomic structure, chlorine has 17 protons and 17 electrons. These electrons are organised into three basic electron shells. The first electron shell has two electrons, whereas the second electron shell has eight electrons. Finally, there are 7 electrons in the valence shell. As a result, the valency of chlorine is frequently assumed to be 7.
Chlorine (Cl)
Chlorine is a chemical element that is represented by the symbol Cl. Chlorine is present in the 17th Group (Halogen Group) and 3rd Period of the Periodic table. Chlorine is the second lightest halogen that lies between Fluorine and Bromine in the halogen group. Chlorine is a yellow-green, pungent-smelling gas at room temperature with an atomic number of 17 and an atomic mass of 35.45. Chlorine is used as a Disinfectant to clean swimming pools etc but is a toxic, corrosive gas that can be irritating to the eyes and respiratory system when coming in direct contact.
