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.
In the very massive stars, the reaction chain continues to produce elements like silicon upto iron. Elements higher than iron cannot be formed through fusion as one has to supply energy for the reaction to take place. However, we do see elements higher than iron around us.
