Potassium (K) is an atomic metal with nineteen atoms. It is essential for the health of both plants and animals. It shines immediately after cutting, but quickly darkens.
- Potassium is the seventh most abundant element in the world.
- First discovered by Sir Humphry Davy in 1807.
- Potassium is the first elemental metal obtained by electrolysis.
- It makes up about 1.5% of the Earth’s crust.
- Potassium does not exist in nature as a pure element.
- Found in nature only in Ionic salts and some minerals.
- They are formed by electrolysis of hydroxide or chloride.
- Potassium is the second densest metal after lithium.
- Potassium is a soft metal and can be easily cut by slicing.
- Argon or other suitable oil; used to store pure potassium, otherwise it will darken quickly.
- Potassium usually reacts with water.
-Reacts with hydrogen in water and generates enough heat to ignite the hydrogen.
- Potassium also reacts with oxygen in water and air.
- Its salts light purple.
-Because it is vital for plant cells,they consume potassium from the soil.Therefore, one of the main industries requiring 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” potassium ” means potassium extracted with wood ash. And in early times it was used to make soap.
-Also known as the eighth most common item in the human body.It accounts for 0.20% to 0.35% of body mass.
- Depletion of potassium from the body can lead to hypokalemia, which can be fatal.
Symptoms include muscle cramps, weakness and irregular heartbeats, according to the University of Maryland Medical Center Nov. High potassium, called hyperkalemia, causes similar symptoms.
‘However, your potassium levels may be off without these extreme symptoms. A 2008 study published in the Journal of Hypertension found that some blood pressure medications can lead to low potassium levels, which in turn increases the risk of Type 2 diabetes.
- Potassium is one of the alkali metals, which is a reactive metal with a value of 1.
- Due to its high reactivity, potassium is not found free in nature. It is formed by a supernova through the R-process and forms on Earth dissolving in seawater and Ionic salts.
-A lesser-known use of potassium is a portable source of oxygen. Potassium superoxide (KO2) is an orange solid used to release oxygen and absorb carbon dioxide in the respiratory system for submarines, spacecraft, and mines.
- The melting point of potassium is 63.4 oC or 336.5 K, and the boiling point is 765.6 oC or 1038.7 K. This is why potassium is solid at room temperature.
- Potassium metal has a density of 0.89 grams per cubic centimeter.
- The word ” potash “comes from” potash”, which goes back to the original method of production of these salts. Plants are rich in potassium, so people will collect wood ash and remove potassium salts in fertilizer use. According to the RSC, in the modern day, 35 million metric tons of potassium are extracted from the world each year.
- When potassium compounds burn, they emit a lilac or violet flame color. It burns in water, as in sodium. The difference is that sodium is more likely to burn with a yellow flame and break up and explode! When potassium burns in water, the reaction releases hydrogen gas. The heat of the reaction can ignite the hydrogen.
- Potassium is used as a heat transfer medium. Salts are used for fertilizer, oxidizer, colorant, strong bases to form, salt substitute and many other applications.
- Potassium cobalt nitrite is a yellow pigment known as cobalt yellow or Aureolin.
- The name of potassium comes from the English word for potash. The Arabic Latin calium for alkali and K derived from Arabic Qali is the symbol for potassium. Potash and alkali are two potassium compounds known to man since ancient times.
