Sodium
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an essential element for human health and is found in many minerals and compounds.
Properties of Sodium
- Physical Properties: Sodium is a soft metal that can be easily cut with a knife. It has a shiny, silvery-white appearance. Sodium has a low melting point and boiling point.
- Chemical Properties: Sodium is highly reactive and quickly tarnishes when exposed to air. It reacts vigorously with water, producing hydrogen gas and a solution of sodium hydroxide.
Uses of Sodium
Sodium has a wide range of uses, including:
- As a component of table salt (sodium chloride), which is essential for human nutrition.
- In the production of various chemicals, such as sodium hydroxide and sodium carbonate.
- In the manufacturing of soaps and detergents.
- As a coolant in nuclear reactors.
