Everything Matters: Tales from the Periodic Table:  Sodium: Ron Hipschman (Clip)
Running Time:
00:38:13
Essential, explosive sodium is a soft, silvery alkali metal that roils in water, releasing clouds of hydrogen gas that fan its yellow flames. It reacts with most elements, and is naturally found only in compounds, such as sodium chloride, or common salt. Ancient Egyptians knew sodium from natron, a mix of salts prized for cleaning, personal hygiene, and preservation, particularly in mummification. Humphry Davy first isolated the element from caustic soda in 1807, naming it sodium; Jakob Berzelius preferred natrium, hence its symbol (Na). As a metal, liquid sodium cools nuclear reactors, and sodium-vapor lamps bathe streets at night in yellow, monochromatic light.

Everything Matters: Tales from the Periodic Table:  Carbon: Ron Hipschman (Clip)
Running Time:
00:20:00
Emerging from inside of stars, carbon is the fourth most abundant element in the universe, and the basis for all life on Earth. Polyamorous, it loves to bond, exchanging four of its electrons with atoms of itself and other elements to create an endless variety of chemistry, from DNA chains to soccer-ball shaped fullerenes to atom-thick sheets of graphene. As diamond, carbon is hard and abrasive, as graphite, soft. When its bonds are broken, carbon readily moves from one partner to the next, cycling between oceans, atmosphere, flora, fauna, soil, rocks, and fossil deposits deep below ground.
