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.
Sodium element block free#
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.
