Sodium (Na)
Although recognized in compounds, sodium was first isolated in 1807. Sodium is fairly abundant in the sun and stars, the fourth most abundant element on Earth, and the most commonly found alkali metal.
Sodium is never found free in nature. It is a soft, bright, silvery metal that floats on water. It can ignite spontaneously in water, and normally will not ignite in air at temperatures below 115°C. Its most common compound is sodium chloride (table salt), but it occurs in soda niter, cryolite, amphibole, zeolite, and many other minerals.
Sodium compounds are important to the paper, glass, soap, textile, petroleum, chemical, and metal industries.
