The Washington tree, located in the Giant Forest Grove in Sequoia National Park provides a good example of the aforementioned phenomena. This tree was the second largest tree in the world (only the General Sherman tree was larger) until just a few years ago.
A halogen is a representative element from group VII in the periodic table. More specifically, Fluorine, Chlorine, Bromine, Iodine, and Astatine. Astatine is a very unstable radionuclide so is not normally dealt with. A halide is a chemical compound of halogens bonded to more electro positive elements.
Halogenation Halogenation is the replacement of one or more hydrogen atoms in an organic compound by a halogen (fluorine, chlorine, bromine or iodine). Unlike the complex transformations of combustion, the halogenation of an alkane appears to be a simple substitution reaction in which a C-H bond is broken and a new C-X bond is formed.
