5 Οκτ 2024 · Learn about the physical and chemical properties of chlorine, a greenish yellow gas that is two and a half times heavier than air. Find out how chlorine reacts with hydrogen, metals, nonmetals, and organic compounds, and how it forms chlorides and oxyacids.
Chlorine is a yellowy-green dense gas with a choking smell and a toxic effect. It is used as a disinfectant, a bleach, and a versatile chemical reagent in many industries and organic reactions.
5 Οκτ 2024 · Chlorine is a greenish yellow gas that belongs to the halogen group of elements. It is highly reactive and corrosive, and it is used to sterilize water, bleach paper, and produce sodium chloride (table salt).
Chlorine is a chemical element; it has symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
7 Νοε 2019 · Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
PRONUNCIATION CLOR-een. Chlorine is a member of the halogen family. Halogens are the elements that make up Group 17 (VIIA) of the periodic table, a chart that shows how elements are related to one another. They include fluorine, bromine, iodine, and astatine. Chlorine is highly reactive, ranking only below fluorine in its chemical activity.
At room temperature, pure chlorine is a yellow-green gas. Chlorine is easily reduced, making it a good oxidation agent. By itself, it is not combustible, but many of its reactions with different compounds are exothermic and produce heat.
