![]() Moreover, iron is the metal at the active site of some redox enzymes that deal with cellular respiration and oxidation, and reduction in plants and animals. These are two types of proteins that play essential roles in vertebrate metabolism. Typically, the adult human body contains around 4 grams of iron, mostly contained in hemoglobin and myoglobin. The crystal structure of iron can be described as body-centered cubic, and there is another possible crystal structure known as face-centered cubic structure. Iron metal is a ferromagnetic metal, and its thermal and electrical conductivity are also high. The +2 state is ferrous, while +3 is ferric. Moreover, the most stable and common oxidation states of iron are +2 and +3. Similarly, it has high melting and boiling points: 1538☌ and 2862☌, respectively. Further, it has a lustrous metallic appearance and occurs at solid-state under standard temperature and pressure. Iron is very common on earth, both in the outer and inner core. Iron is a chemical element having the symbol Fe and atomic number 26. In addition, sodium is used as an alloying metal for anti-scaling agents. Further, metallic sodium is useful in the production of sodium borohydride, sodium azide, indigo, and triphenylphosphine. Besides, metallic sodium is important for the production of sodium-containing compounds such as sodium chloride, sodium hydroxide, and sodium carbonate, which are produced annually for different needs. For instance, the sodium cation is the major cation in extracellular fluid in animals. Sodium is an essential element for animals and some plants. Upon dissolution, these salts form a sodium cation having a +1 electric charge. Almost all sodium salts are water-soluble. Sodium mainly occurs in minerals like feldspar, sodalite, and rock salt. Further, this metal can be recognized as the 6th most abundant element on Earth’s crust. This metal exists in the form of salts from which we can extract the pure metal. However, we cannot find any free sodium atoms in nature because of their high reactivity. Therefore, one sodium atom can remove one electron in order to get a stable, noble gas electron configuration. The electron configuration of this chemical element is 3s1. We can categorize sodium as an alkali metal because it is a group 1 metal. Sodium can be found in group 1 and period 3 of the periodic table of elements, where it exists as an s-block element. The chemical symbol of this atom comes from its Latin name Natrium. Sodium is a chemical element having atomic number 11 and the chemical symbol Na. However, these two metals are different from each other and have differences in both chemical and physical properties as well as appearances. The key difference between sodium and iron is that sodium is a soft metal and a non-transition metal with low melting and boiling points and whereas iron is a hard metal and a transition metal with very high melting and boiling points.īoth sodium and iron are metals. ![]()
