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. |
