The density of alkali metals increases with improve in atomic number, nonetheless, sodium not like the other alkali metals has a higher density as compared to potassium.
Sodium has 13 isotopes, of which only one isotope is stable.
Sodium cannot exist freely in nature and when brought in touch with air, readily oxidizes and kinds oxides.
When sodium is introduced in touch with water, it explodes, forming sodium hydroxide along with the release of a large amount of heat.
Sodium is the fourth most considerable aspect and makes up almost 2.6% of the Earth’s crust. It’s also relatively abundant in stars.
Among the numerous attention-grabbing information about sodium, one is that the sodium aspect is extremely reactive, which makes the storage of pure sodium a Herculean job. The very best method to store sodium safely is by immersing it into liquid hydrocarbons, corresponding to kerosene.
While working within the lab, students and lab assistants are expected to take the piece of elemental sodium out of the kerosene and lower a small piece with the knife. Thus, though elemental sodium bears semblance to a small rock, it’s soft enough to be reduce by a blunt knife.
Sodium is used in some alloys, so as to improve their structure, and is used to descale the floor of many metals. Metallic sodium is used within the means of purifying some reactive metals, equivalent to zirconium from their compounds.
Sodium is used in several industries akin to chemical, metal, paper, petroleum, textile, and so on. the place it is used to arrange sodium compounds comparable to frequent salt, baking soda, borax, sodium nitrate, and so forth.
Sodium can also be used to make vapor lamps, which are utilized in avenue lights. Vapor lamps can produce mild from electricity very effectively. It acts as a heat transfer liquid and is utilized in some nuclear reactors.
Sodium is a big ingredient in soap manufacturing along with fatty acids.
More than 90% of the sodium present on the Earth is in the form of salt. Let’s discover out more about salt.
