This element is the heaviest element found in the molecule X-gal.
This element is the heaviest element found in the molecule X-gal. In mass spectrometry, the presence of this element is easily seen because of an M-plus-2 peak at the same height. This element's binary acid adds anti-Markovnikov to an alkene in the presence of peroxides. Its (*) ethidium salt intercalates DNA and fluoresces during gel electrophoresis. Diphenyl ethers with many atoms of this element attached are used as a flame retardant. Double bonds in compounds are qualitatively detected by adding this element, since the solution will turn from brown to colorless. This element of group 17 has an electron configuration ending with 4p5. For 10 points, name this halogen that presents at room temperature as a reddish brown liquid.
