"The Atom"

What are  the Properties of Potassium? Definition of Potassium
What is the definition of Potassium? It is a soft, silver-white, highly or explosively reactive metallic element that occurs in nature only in compounds. The Physical and Chemical Properties are the characteristics of a substance, like Potassium, which distinguishes it from any other substance. Most common substances exist as States of Matter as solids, liquids, gases and plasma.

Refer to the article on Potassium above for additional information and facts about this substance.

Potassium Properties - What are the Physical Properties of Potassium?
What are the Physical Properties of Potassium? The Physical properties of Potassium 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 Potassium are as follows:

  • Color : Silver-white
  • Phase : Solid
  • Melting point : Melting point of 63C (145F) - very low for a metal
  • Color : Silvery-white metal
  • Density  : Less than water

Potassium Properties - What are the Chemical Properties of Potassium?
What are the Chemical Properties of Potassium? 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 Potassium are as follows:

  • Chemical Formula : K
  • Reactivity with water : It reacts with water violently and gives off hydrogen gas
  • Reactivity : It reacts readily with all acids and with all non-metals, such as sulfur, chlorine, fluorine, phosphorus, and nitrogen
    Highly or explosively reactive
  • Compounds : Useful compounds include the bromide, KBr, the cyanide, KCN, Potassium carbonate K2CO3. Substances containing potassium impart a purple color to a flame
  • Oxidation : Rapidly oxidizes in air
  • Alloys : Alloyed with sodium as a cooling medium in nuclear reactors
