What are 2 characteristics of chlorine?
Physical and chemical properties
- Chlorine is a greenish yellow gas at room temperature and atmospheric pressure.
- Chlorine has a high electronegativity and a high electron affinity, the latter being even slightly higher than that of fluorine.
What makes chlorine unique or special?
It is the second lightest halogen, after fluorine. Like other halogens, it’s an extremely reactive element that readily forms the -1 anion. Because of its high reactivity, chlorine is found in compounds. Free chlorine is rare but exists as a dense, diatomic gas.
What are 2 common uses for chlorine?
Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides. About 20% of chlorine produced is used to make PVC.
Do humans need chlorine to survive?
Chlorine is needed for the survival of animal life in the form of table salt (NaCl). Our body’s use it to help us digest food, move our muscles, and fight off germs.

What is the difference between chloride and chlorine?
• Chloride is the reduced form of chlorine. Chloride has 18 electrons compared to seventeen electrons of chlorine, and both have seventeen protons. Therefore, chloride has a -1 charge whereas chlorine is neutral. • Chlorine is more chemically reactive than chloride.
What is the element name for chlorine?
Chlorine (Cl), chemical element, the second lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Chlorine is a toxic, corrosive, greenish yellow gas that is irritating to the eyes and to the respiratory system.
What is chlorine gas?
Chlorine (Cl₂) is a greenish-yellow gas with a pungent, irritating odor. Exposure to low levels of chlorine can result in nose, throat, and eye irritation. At higher levels, breathing chlorine gas may result in changes in breathing rate and coughing, and damage to the lungs. Additional symptoms of exposure to chlorine can be severe.
What is chlorine chloride?
Under standard conditions, chlorine exists as a diatomic molecule. Chlorine is a highly toxic, pale yellow-green gas that has a specific strong smell. In nature, chlorine is most abundant as a chloride ion. Physiologically, it exists as an ion in the body. The chloride ion is an essential anion that the body needs for many critical functions.
