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.
Their is no relation of radioactivity and tendency to foming compounds . Down to the francium the reactivity must be slightly decrease due to the heavy nuclei. So cesium is the most reactive element in group 1 and whole the perodic table.
