Sodium was first isolated from sodium hydroxide by Humphry Davy in 1807.
Most of its salts are water soluable.
Of the twenty known isotopes of sodium, only one—Na-23—is stable.
Sodium is a vital element for living organisms.
Sodium compounds are used in nearly every form of industry.
Another isotope, Na-24, has a half-life of 20.2 microseconds.
Powdered sodium can spontaneously combust in the presence of oxygen.
Elemental sodium can be very dangerous since it generates inflammable hydrogen and sodium hydroxide.
Sodium in its compound forms has a long and important history.
Typical fire extinguishers are ineffective on sodium fires and can actually increase the emergency.
It has been used as a form of currency, medical treatments, and trade product for thousands of years.
Chemical properties all are those properties that are noticeable only when any reaction is occurring between sodium and some other chemical substance. As per the periodic table, less reactive compared to potassium and sodium is more reactive compared to lithium.
Sodium quickly reacts with oxygen to make sodium oxide. Whenever pure type of sodium comes in contact with air, it make sodium oxide quickly and this oxide forms a white coating and shields the underlying metal from any further reaction. Therefore it is often stored in oil to avoid it from reacting with oxygen.
Reaction of sodium with hydrogen at a temperature of over 392 °F (200 °C) results in the creation of sodium hydride ( NaH). Sodium hydride is a substance which decomposes however does not melt at 752 °F (400 °C).
Sodium (Na) is a silver-white alkalai metal having an atomic number of 11. It is a soft metal that does not take place naturally in the world as a free element.
The metal tarnishes to make a white coating of sodium hydroxide and sodium carbonate very rapidly at standard conditions.
Pure sodium at standard conditions can effortlessly be cut with a knife, despite being a metal.
One of the most common compound of sodium is sodium chloride, NaCl, or ordinary table salt.
At higher elevations, the tarnish takes on a black, red transparent, or clear transparent coating, according to the elevation.
Sodium chloride is abundantly existing in mines and in seawater in the world.
Sodium chloride has been regarded as a part of animal diets since prehistoric times.
