What are some cool facts about potassium?

What are some cool facts about potassium? Potassium is a soft silvery-white alkali metal. It has 20 neutrons and 19 protons in its structural arrangement. It melts at the temperature of 336.8 K and boils at 1047.15 K. Even though this element is the seventh most abundantly found element, it is difficult to obtain it from its minerals.

What are 5 common uses for potassium?

Potassium: uses

  • The superoxide KO2is used in breathing apparatus where moisture in the breath and carbon dioxide reacts with it to release oxygen [2KO2+ H2O + 2CO2→ 2KHCO3+ O2]
  • the alloy of potassium with sodium (NaK) is used as a heat-transfer medium in nuclear reactors.
  • fertilizers – usually as the chloride, sulphate, nitrate, or carbonate

What is the origin of potassium? Potassium was discovered by Sir Humphrey Davy in 1807 at England. Origin of name: from the English word “potash” (pot ashes) and the Arabic word “qali” meaning alkali (the origin of the symbol K comes from the Latin word “kalium”).

What is the history of potassium? Potassium is a very reactive metal and one of the least dense metals in the periodic table. It has a body-centered cubic crystal structure and 1 oxidation state. The element oxidizes and tarnishes quickly when exposed to air. Potassium was first discovered in 1807 by Humphry Davy.
