Sodium(Na) and Rubidium(Rb). The common features of Potassium(K), Sodium(Na) and Rubidium(Rb) are...
1. They are all in the Alkali family.
2. They are active and reactive.
3. They will have reaction with water.
4. They have soft texture and can cut with butter knife.
5. Sodium(Na) is above Potassium(K) and Rubidium(Rb) is below Potassium(K).

1. About 95% of potassium goes into fertilizers, and the rest goes mainly into making potassium hydroxide (KOH) process and goes to manufactures of glass, for example the television. Moreover, potassium hydroxide is used to make liquid soap and detergents, and few potassium chloride goes into pharmaceuticals, medical drips and saline injections.
2. People that have hypertension and some old people can't absorb that much Sodium(Na), therefore, instead of absorbing salt(NaCl), hypertensive patients absorb low sodium salt(KCl), which potassium replace sodium.
3. Athlete eat bananas after they exercise to supplement potassium ions for their muscles and nerves. Potassium ions are mainly metabolize by kidney and excrete from urine.

1. Potassium won't exist in the natural world, since it's just too reactive, moreover, it will react with all nonmetal materials. Therefore, instead of existing in the real life, it present in the form of metal salt. Furthermore, potassium is obtained from potassium chloride, the chloride is melted and contain as sodium vapor. Potassium was stored in mineral oil to avoid it from oxidation.
2.  Potassium is one of the most soft metal in the nature, you can cut it with butter knife when stored at room temperature. The reason is because texture of potassium is very soft, different than other metal(copper, gold, iron).
3. The burning point of potassium is extremely low, therefore, it will react with water by burning reaction and produce H₂.
4. Potassium is one of the most abundant metal on earth, it is in everything around us, according to researches,  about 1.6% of the earth's crust includes potassium moreover, potassium ions are beneficial for plant nutrition, therefore, potassium plays a significant role in fertilizers.
5. Out of all metals, potassium was the first metal to be isolated through electrolysis. In 1807, Davy electrolyzed dry molten caustic potash or potassium hydroxide, finally, potassium was collected at the cathode end of the process. Other metals followed suit after potassium.
