Properties

Sodium is a silvery white metal with a waxy appearance. It is soft enough to be cut with a knife. When first cut, the surface is bright and shiny, but it quickly becomes dull as sodium reacts with oxygen in the air to form sodium oxide (Na2O). Sodium's melting point is 208.1°F (97.82°C), its boiling point is 1,618°F (881.4°C), and its density is 0.968 grams per cubic centimeter. Sodium is a good conductor of electricity.

Sodium is a very active element that combines with oxygen at room temperature and burns with a brilliant golden-yellow flame. It reacts violently with water to produce hydrogen gas, which may...
