Potassium Facts

Potassium Facts
Potassium (K) is a metal with an atomic number of nineteen It is essential for the health of both plants and animals. It is silver immediately after being cut, but quickly tarnishes.
Interesting Potassium Facts:
Potassium is the seventh most abundant element on Earth.
It was first isolated by Sir Humphry Davy in 1807.
Potassium was the first elemental metal to be found through electrolysis.
It makes up roughly 1.5% by mass of the Earth's crust.
Potassium is not available in nature as a pure element.
In nature, it is only found in ionic salts and in some minerals.
It is created through the electrolysis of its hydroxide or its chloride.
Potassium is the second least dense metal after lithium.
Potassium is a soft metal and can very easily by sliced.
Argon or another suitable oil is used to store pure potassium, otherwise it will tarnish quickly.
Potassium usually burns in a reaction with water.
It reacts with the hydrogen in the water and generates enough heat to ignite the hydrogen.
Potassium also reacts with the oxygen in water and in air.
Its salts burn with a light purple color.
Because it is vital for plant cells, crops readily deplete potassium from the soil.
For this reason, one of the major industries to require potassium is the fertilizer industry.
Potassium has twenty-four known isotopes, but only three of them occur in nature.
The K-39 isotope is the most abundant of the three, making up more than 93% of the isotopes.
The term "potash" refers to potassium extracted from wood ash, and it was used in early times to make soap.
It is also common in the human body as the eighth most common element.
A depletion of potassium from the body can lead to hypokalemia, which can be fatal.
