The first element of the fourth row (period) is potassium the name potassium comes from a substance called potash that compound that has been used for hundreds of years and has the chemical formula koh even though we have been using potash for centuries, davy officially discovered potassium in 1807.
Chemical properties - potassium (chemical symbol k, from latin kalium) oxidizes very quickly, and reacts with water very violently to form potassium hydroxide, via the following reaction: k + h2o - h2 + koh this reaction is exothermic enough to cause the hydrogen gas created to combust in order to keep potassium from reacting with.

Quick answer potassium belongs to the family of elements called the alkali metals this is the first group of elements on the periodic table because they all are very reactive and have a single electron in their outermost energy level. Hyperkalemia is the medical term for blood potassium levels that are too high potassium is a chemical element that is essential for life it is especially important for the normal functioning of organ systems that rely on the transmission of electrical signals—the heart, muscles, and the nerves. As with sodium, a number of modern languages still refer to potassium as kalium, and the name lends the element its chemical symbol, k iron – ferrum (fe) iron’s latin name, ‘ferrum’, gives it its symbol fe it simply means ‘iron’ or ‘sword’, and is possibly of semitic origin the element is known by a myriad of various names in different.
