Sodium Sodium's History Physical and Chemical properties
of Sodium: Soft
Very Malleable
sodium is a solid at room temperature
Reacts explosively with water and oxygen therefore, sodium and other alkili metals must be kept in a mineral oil, so it doesn't react with the water vapor in the air.

traits continued

silver - a white metallic element
when sodium is kept in the open the open air, it becomes dull and gray because of its reaction with water.
sodium's boiling point is 883 degrees Celcius.
sodium is a good conductor of electricity, which means that an electric current can pass through sodium easily without any resistance
sodium is never found in its metallic states because it is always a compound.

Modern Uses: sodium mixed with chorine makes table salt
sodium vapor makes the yellow color in street lamps
sodium carbonate makes hydroxide soap cleaner
sodium bicarbonate makes baking soda
sodium is used to flavor food substances.
sodium is used as a heat exchange medium in nuclear power plants Extra Facts: sodium makes up 2.6% of our earth
in the ocean sodium has an estimated abundance of 1.08 grams per liter
sodium is the 6th most abundant element
the nuclear power industry uses sodium as a coolant for reactors.
too much sodium can cause heart and kidney diseases.

Meg Vischer Discovered in 1807, by Sir Humphrey Davy
Davy created sodium by the elecrolysis of very dry molten sodium hydroxide
the name sodium comes from the Latin word Natrium that is why the Chemical symbol for sodium is NA.
sodium was sometimes used as a cure for headaches.
As early as 1370 B.C. ancient Egyptians were making glass by heating up and melting sodium.

Atomic Number: 11
Atomic Mass: 22.98977 amu
Sodium is a metal that is part of Group 1, the Alkali Metals.
