Top 17 interesting facts about Potassium
Potassium was discovered in 1807 by Sir Humphrey Davy.
Its symbol K comes from the Latin word "kalium" and its name derives from the word "potash".
Potassium's melting point is at 63.65 °C (336.8 K, 146.57 °F) and its boiling point is at 774.0 °C (1047.15 K, 425.2 °F).
Potassium is silvery and very soft metal that oxidizes very fast in the air.
Potassium reacts very violently with water.
The reaction with water generates a lot of heat that ignite the hydrogen emitted by the reaction.
Potassium has 24 isotopes but only three of them occur naturally and are stable 39-K, 40-K, and 41-K.
The potassium's isotope 40-K is radioactive.
In nature, potassium can be found only in ionic salts.
Potassium ions are used by all living cells.
Potassium is very less dense; only lithium is lesser dense than potassium.
Potassium reacts very easy with oxygen forming potassium peroxide and with hydrogen forming potassium hydroxide.
Potassium is created by the type 2 supernovas.
Potassium represents 2.6% of the Earth's crust.
It is the 7
most abundant element in the Earth's crust, 17
most abundant in entire planet and 20
most abundant in our solar system.
Potassium is used as a fertilizer in agriculture.
Potassium is an important nutrient in human life so it has many applications in food industry.
