where is sodium found and how is it obtained

Although sodium is the sixth most abundant element on earth and comprises about % of the earth's crust, it is a very reactive element and is never found free.

It's crucial for blood-pressure control and the functioning of the nervous system. When mixed with water, sodium reacts spectacularly. The heat is so intense that it ignites the hydrogen gas, creating an impressive explosion. Scientists have even caught this reaction on high-speed video, capturing the blast and explaining why the reaction happens so quickly. All those positive charges repel each other, tearing the sodium apart and creating more surface area for an even bigger reaction: ka-boom. Sodium is an alkali metal, found on the leftmost side of the Periodic Table with its compatriots: lithium, potassium, rubidium, cesium and francium. What all of these alkali metals have in common is a single electron in their outermost shell.

Much like lithium, sodium is a light, very soft, silvery-white metal. It is even softer than lithium and can be cut with a knife. Sodium is very reactive with air and water. If a sufficient quantity comes in contact with water, sodium can actually explode. Sodium is a very common element in the universe, being the fourth most abundant element on the Earth and very common in stars. Sodium light spectra is used by astronomers to identify stars that are similar to our Sun. The metal itself is used in making drugs, organic compounds and dyes.

Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties.

Members of a group typically have similar properties and electron configurations in their outer shell. Period A horizontal row in the periodic table.

It is never found in its pure form because it is so reactive. It is only found in compounds such as sodium chloride (NaCL) or table salt. Sodium chloride is found in.

Most people have never seen sodium metal. But it is almost impossible not to see many compounds of sodium every day. Ordinary table salt, baking soda, baking powder, household lye such as Drano , soaps and detergents, aspirin and other drugs, and countless other consumer products are sodium products. Sodium is a member of the alkali metals family. The alkali family consists of elements in Group 1 IA of the periodic table.

It is a soft, silvery-white, highly reactive metal. Its only stable isotope is 23 Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars , sodalite , and rock salt NaCl. Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in by the electrolysis of sodium hydroxide.

Sodium Na , chemical element of the alkali metal group Group 1 [Ia] of the periodic table. Sodium is a very soft silvery-white metal. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2. It occurs abundantly in nature in compounds , especially common salt sodium chloride NaCl which forms the mineral halite and constitutes about 80 percent of the dissolved constituents of seawater. In Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide NaOH.
