Sodium is combined with chlorine common as table salt.
In nature, the element sodium is a white and highly reactive to other elements and compounds. Sodium is an essential element of constituent organisms.
history
Sodium is an element that is easily found in nature. In 1807, Sir Humphrey Davy managed to separate the pure sodium and analyze it as an isolated element for the first time.
In the course of human history, sodium chloride (table salt) is a precious commodity that is commonly used in religious ceremonies and trading in Greek culture, Egypt, and the ancient Arabs.
type
In chemical terms, the different types of elements referred to as isotopes. Each isotope has a different atomic mass and therefore have different properties.
Sodium has thirteen isotopes, and the only one that is stable in its natural form is 23NA.
22NA and specific isotope 24Na is formed as a result of exposure to cosmic rays that give scientists information about the berharag geological events.
When a person is exposed to nuclear radiation, 23NA converted into 24Na in the blood can be measured to see how much radioactive material that affects the person.
warning
When handling pure sodium, so caution is needed because of the nature of this unstable element. Keep away from water because sodium can trigger exothermic reaction.
The reaction of sodium with water will also create flammable hydrogen gas, and sodium hydroxide that will irritate the skin.
Sodium at room temperature has a silvery white color and soft to be cut with a knife.
Sodium is an element that is quite solid, more solid than potassium which has a larger atomic numbers.
The element sodium notoriously unstable. Sodium atom has eleven electrons.
