This can take up a huge amount of the body's energy - sometimes as much as 40 per cent. Density (g cm−3)

This is something you will have seen in all built up areas in the form of street lamps, which use sodium to produce the unnatural yellow light bathing our streets.

The mass of an atom relative to that of carbon-12.

It is used as a water softener. The atomic number of each element increases by one, reading from left to right. Text © The Royal Society of Chemistry 1999-2011

Sodium is important for many different functions of the human body. Like the other alkali metals, it has a very distinctive flame test - a bright orange colour, from the D-line emission.

The percentage of the world reserves located in the country with the largest reserves.
Get exclusive access to content from our 1768 First Edition with your subscription. The temperature at which the liquid–gas phase change occurs. Each allotrope has different physical properties. Elements are organised into blocks by the orbital type in which the outer electrons are found. Images © Murray Robertson 1999-2011

The alkaline solutions it forms when dissolved in water neutralize acids in various commercial processes: in petroleum refining, it removes sulfuric and organic acids; in soapmaking, it reacts with fatty acids.
A horizontal row in the periodic table.

The percentage of an element produced in the top producing country. Where more than one isotope exists, the value given is the abundance weighted average. It’s a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF).

Sodium and hydrogen react above 200ºC (390ºF) to form sodium hydride. Phone: +971 4 429 5853 e-mail: info@lenntech.com, Copyright © 1998-2020 Lenntech B.V. All rights reserved, Plant Inspection & Process Optimalisation, Separation and Concentration Purification Request. A vertical column in the periodic table. Sodium nitrate is used as a nitrogenous fertilizer and as a component of dynamite. Sodium hydroxide is also used in biodiesel manufacture, and as a key component in products that remove blockages from drains.

Contact of sodium with water, including perspiration causes the formation of sodium hydroxide fumes, which are highly irritating to skin, eyes, nose and throat.

In medieval Europe, however, sodium carbonate was also used as a cure for headaches, and so took the name sodanum, from the Arabic suda, meaning headache.

It's easy to accuse the scientists who produce new, very heavy elements of being chemistry's train spotters. Low = substitution is possible with little or no economic and/or performance impact. This may cause sneezing and coughing. Even so it is highly abundant, accounting for around 2.6 per cent of the earths crust by weight. This pictogram meant divine or pure and its name is the root of the word natron, which was used to refer to washing soda, or sodium carbonate decahydrate, as we would know it today.

Values are given for typical oxidation number and coordination.

Data for this section been provided by the British Geological Survey. The temperature at which the liquid–gas phase change occurs. Solutions of NaOH are used in the treatment of cellulose and in the manufacture of many chemicals.

For example, it helps cells to transmit nerve signals and regulate water levels in tissues and blood.

Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust.

This is approximately the sum of the number of protons and neutrons in the nucleus. In 1807, at the Royal Institution, London, a few days after isolating potassium for the first time, he isolated sodium for the first time by electrolysis of dried sodium hydroxide, which had been very slightly moistened.

Very severe exposures may result in difficult breathing, coughing and chemical bronchitis.

The sum of the oxidation states within a compound or ion must equal the overall charge. This involves sodium (and its big brother potassium) diffusing through cell membranes.

The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. The most common compound is sodium chloride. Its violent reactive nature contrasted with its use by amorous butterflies. Shop for Mens & Women's Footwear, Apparel & Skateboarding Gear on the Official Website
