Synopsis: The iron triangle contains the elements iron, cobalt, and nickel. It describes the similarities between the three elements. They are all located in period 4. They are ferromagnetic due to the fact that when put in an environment at curie point temperature the lining that allows them to be paramagnetic is broken down. They are different in oxidation states. The elements are known as the iron triangle because they share the properties of iron, which is shiny in color and easily reacts with other metals

Keywords: Looked up the words iron triangle, ferromagnetism, and iron on Google and there appears to be no cases of plagariasm.

Review Details:The module appears to be missing some important information regarding the similarities of the metals within the iron triangle. The module is lacking in overall length. The effectiveness might be improved by adding illustration and videos. You need to include a section for references, outside links, and problems.
