What is Potassium? Potassium is a soft silvery Alkali metal. This element is the 7th most abundant on earth. This makes up 2.4% of the earth's crust. You would not be able to find Potassium in nature, because Potassium was the first element to be founded by electrolysis. ( electrolysis is decomposition of an chemical element by passing an electric current through it.) This element can be found in Potash. This is what is used to fertilize crops. Potash is mined in 2 U.S states, California and New Mexico. Potassium is very reactive, given that it has a valance electron of only 1. This element is important because all living things need it to function properly. Potassium is found in bananas, tomatoes, salt, dried fruit, and suprisingly, Potato Chips. Potassium is a very important element to the earth because we need it to live and to function in life.
