20 Σεπ 2024 · Iron (Fe), chemical element and one of the transition elements, the most-used and cheapest metal. Iron makes up 5 percent of Earth’s crust and is second in abundance to aluminum among the metals. Iron, which is the chief constituent of Earth’s core, is the most abundant element in Earth as a whole.
9 Μαρ 2020 · Iron is a chemical element with many different uses in the industries. It is widespread on our planet. The chemical symbol of Iron is represented by Fe symbol. Iron lies in the category of transition metals so you cannot easily find it in its pure form. When Iron gets into contact with oxygen, it gets oxidized.
Iron’s ability to act as a central atom in coordination compounds is critical in bioinorganic chemistry. For example, in hemoglobin and myoglobin, iron binds reversibly with oxygen molecules, allowing these proteins to carry oxygen through the bloodstream and muscles.
