Definition of Sodium
What is the definition of Sodium? It is a soft, light, extremely malleable silver-white metallic element that reacts explosively with water, is naturally abundant in combined forms, especially in common salt, and is used in the production of a wide variety of industrially important compounds. The Physical and Chemical Properties are the characteristics of a substance, like Sodium, which distinguishes it from any other substance. Most common substances, like Sodium, exist as States of Matter as solids, liquids, gases and plasma. Refer to the article on Sodium for additional information and facts about this substance.

Sodium Properties - What are the Physical Properties of Sodium?
What are the Physical Properties of Sodium? The Physical properties of Sodium are the characteristics that can be observed without changing the substance into another substance.

Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Sodium are as follows:

  • Color : Silver-White
  • Malleability : Capable of being shaped or bent
  • Ductility : Easily pulled or stretched into a thin wire
  • Luster : Has a shine or glow
  • Conductivity : Good transmission of heat or electricity
  • Softness : Soft enough to be cut with a knife

Sodium Properties - What are the Chemical Properties of Sodium?
What are the Chemical Properties of Sodium? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Sodium are as follows:

  • Chemical Formula : Na
  • Reactivity with water : Reacts explosively with water
  • Oxidation  : Combines with oxygen at room temperature
  • Reactivity with water : Reacts violently with water
  • Flammability : Burns with a brilliant golden-yellow flame
  • Reactivity with acids : Reacts with acids to produce hydrogen gas. Dissolves in mercury to form a sodium amalgam
