In the first transition series of the periodic table, three elements are notably grouped together for their similar physical and chemical characteristics. These elements are known as the iron triad and include iron (Fe), cobalt (Co), and nickel (Ni). The triad is especially recognized for its powerful ferromagnetic properties at room temperature.

According to the reactivity series of metals, potassium is ranked significantly higher than iron, meaning it is more reactive. This fundamental principle of chemistry allows us to answer the question: can potassium displace iron? The answer lies in the relative position of these two elements within this vital chemical hierarchy.
