Isolation: iodine is available commercially so it is not normally necessary to make it in the laboratory. Iodine occurs in seawater but in much smaller quantities than chloride or bromide. As for bromine, with suitable sources of brine, it is recovered commercially through the treatment of brine...

List one use for fluorine, chlorine, bromine, and iodine compounds.Review List the halogens by name, chemical symbol, and atomic weight. What does the term “halogen” mean? What is the outer shell electron configuration for the halogens? What is the physical state of each halogen at room...
Elements can also be grouped into families or groups based on their chemical properties. For example, the halogens (such as chlorine and bromine) are known for their ability to form compounds with hydrogen, while the noble gases (such as helium and neon) are chemically unreactive. ...
Johann Dobereiner created an organization tool for the elements called a triad. Each triad contained three elements that had similar properties. For example, one of Dobereiner's triads contained the elements chlorine,bromine, and iodine because they all formed salt. Dobereiner was not able to pro...
