Potassium

INTRODUCTION

The symbol K stands for Potassium, which is an alkali metal. The physical properties of Potassium is that it is a silver, white metal that is soft that has a melting pointing of 63 degrees c or 145 f. Potassium metal has the ability to float on water as well. This element is very reactive, especially with water and gives off hydrogen gas. Potassium tends to react with acid and non-metals such as sulfur, chlorine, fluorine, phosphorus, and nitrogen. Potassium is found deep in the earth’s crust and is found in a wide selection of minerals. The most essential compound would have to be Potassium Chloride and is typically referred to as potash. That compound is used to make synthetic fertilizers and it is one of the three primary nutrients/macronutrients required in plants. Isotopes are two or more forms of one pure element. They differ according to mass number. There are about 3 naturally occurring isotopes of potassium. This being potassium-39, potassium-40, and potassium-41. Potassium 40 is radioactive.

Story of Potassium

Once upon a time there was a banana. This banana had a wonderful amount of potassium in it! One day, a customer at HI-V saw this banana and decided to purchase it. But before they purchased it they wanted to know how the potassium in the banana reacted to other things. They bought the banana and then proceeded to experiment. To start off, the customer went all out and tried mixing the banana with acid. This indeed was very reactive. The customer went to their garage to grab some chlorine, and decided to mix these two together first. Reactive, once again. It was obvious that oxygen and the potassium had no reactivity, but the customer wanted to know if it was reactive with nitrogen. The customer purchased a tank of nitrogen at a store and tested it with the banana, and yes! It was reactive!
