The potassium found in bananas helps promote bone health!
Potassium is the 7th most abundant element on Earth!
People whose diets are LOW in potassium can get hypokalemia(deficiency of potassium in the bloodstream), which can lead to death.
All plants need potassium to survive. In fact, 90% of all human use of potassium compounds is in plant fertilizers.
Potassium costs:
$40 for 1 gram of PURE potassium
$1.50 for 1 gram of potassium when purchased in a BULK.
The price varies depending on the type of potassium you buy. In some cases, a prescription is needed in order to buy potassium.
Potassium is a METAL.
Also, potassium is a SOLID(normal phase) at room temperature.
What is Potassium?
Potassium 101
Potassium Facts:
Potassium is a silvery-white metal. Potassium belongs to the alkali metal family, which obviously makes it a metal and a solid at its normal state. Its name comes from the English word "POTASH", originally meaning an alkali extracted with water in a pot of burned wood or tree leaves. Potassium's symbol, K, comes from "KALIUM", which is the name of the element(potassium) in Germany and Scandinavia. It was discovered by English chemist Sir Humphry Davy on October 6, 1807 in the Royal Institution, London, England (United Kingdom).
To find the amount of neutrons potassium contains, simply do: atomic mass - atomic number.
The End!
