According to the eighth grade Physical Science textbook, the reason that they differ is because the coinage metals are arranged the way they are so stable and malleable and can be found as free elements in nature. These metals were used widely to make coins, giving them the title of the coinage metals. As for the iron triad, it differs because the elements are used in the process to create steel and other metal mixtures.
iron cobalt and nickel are magnetic the others are not.

Iron, Cobalt, and Nickel are magnetic. The others are not.
Iron Triad (iron,cobalt,nickel)
Chlorine, iodine and another make up the halogen triad.The halogens are:FluorineChlorineBromineIodineAstatineDoesn't sound like a triad to me.
All the elements known at that time could not be arranged as Dobereiner's triad's example: the three elements, nitrogen, phosphorus and arsenic have similar properties. Therefore they can be regarded to form a triad. However, the actual atomic mass if the middle element, phosphorus(P)(31.0u)is much lower than the average or mean(44.45u)of the atomic masses of nitrogen and arsenic. Thus, these three elements do not constitute a Dobereiner triad in spite of their similar chemical properties.
Once a triad has been achieved, Calcium ions get released. Once they're released they bind to troponin, which helps begin muscle contraction.

Dobereiner's triads were not applicable to all set of elements. The triad could be made only for few elements. So they were rejected.
Three chemical elements make up the Iron Triad, iron (Fe), cobalt (Co) and nickel (Ni).These three elements are sometimes given the name Iron Triad because they have some similarities in properties and are located together in the Periodic Table.
