It is used in respiratory equipment and is produced by burning potassium metal in dry air. Potassium superoxide (KO 2) can create oxygen from water vapor (H 2O) and carbon dioxide (CO 2) through the following reaction: 2KO 2 + H 2O + 2CO 2 => 2KHCO 3 + O 2. Potassium carbonate (KHCO 3), also known as pearl ash, is used to make some types of glass and soaps and is obtained commercially as a byproduct of the production of ammonia. Potassium hydroxide (KOH) is used to make soaps, detergents and drain cleaners. It is used in fertilizers, as a salt substitute and to produce other chemicals. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. More popular solutions can be found here: 6 letters: Sodium. Potassium chloride (KCl) is the most common potassium compound. Summary Atomic Number Protons, Electrons and Neutrons in Sodium Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus. The most popular crossword solutions for ELEMENT WITH THE SYMBOL NA are Sodium (6 letters). Potassium forms many important compounds. Potassium forms an alloy with sodium (NaK) that is used as a heat transfer medium in some types of nuclear reactors. To prevent it from reacting with the oxygen and water in the air, samples of metallic potassium are usually stored submerged in mineral oil. Enough heat is produced to ignite the hydrogen gas. It reacts with oxygen to form potassium superoxide (KO 2) and with water to form potassium hydroxide (KOH), hydrogen gas and heat. Pure potassium is a soft, waxy metal that can be easily cut with a knife. Caustic potash, another important source of potassium, is primarily mined in Germany, New Mexico, California and Utah. These minerals are often found in ancient lake and sea beds. MgCl 2♶H 2O), langbeinite (K 2Mg 2(SO 4) 3) and polyhalite (K 2Ca 2Mg(SO 4) 4♲H 2O). With an atomic number of 11, it is represented by the symbol Na in the Periodic table.Potassium can be obtained from the minerals sylvite (KCl), carnallite (KCl A few months after discovering potassium, Davy used the same method to isolate sodium. Metallic potassium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of molten caustic potash (KOH).

Although potassium is the eighth most abundant element on earth and comprises about 2.1% of the earth's crust, it is a very reactive element and is never found free in nature.
