Therefore, we chose those colors to represent SAAC. However, each type of cancer has its own color, and these are listed below:
Reaction of iron with the halogens. Iron reacts with excess of the halogens F2, Cl2, and Br2, to form ferric, that is, Fe(III), halides. This reaction is not very successful for iodine because of thermodynamic problems. The iron(III) is too oxidizing and the iodide is too reducing.
Answer by Chemistry4thewin. Confidence votes 1.6K. The most chemically active non-metal, and the most reactive element overall, is fluorine. Fluorine has an extremely high electronegativity, meaning that it will remove an electron form almost anything. Therefore, it is amazingly reactive, and it even reacts with glass.
