Visit Bodycote’s new Interactive Periodic Table to view this information and more graphically. In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group). Its element symbol is K, its classification is alkali metal, its color is silvery-gray, its atomic number is 19, its atomic weight is 39.0983, its atomic radius is 243 pm, its atomic mass is 39.098, it occurs in a solid state at room temperature, it has a melting point of 336.5 K or 146.1 F (63.4 C. Chemical symbolįrom the Latin Argentum which originally meant shining metalįrom the Latin Aurum which originally meant yellowįrom Cuprum, the Latin name for Cyprus, the Roman source of copperįrom the Latin Hydragyrummeaning liquid silverįrom Natrium, the Latin namefor sodium carbonateįrom the Latin Plumbummeaning soft white metalįrom the Latin Stibiummeaning cosmetic powderįrom Wolfram, an old name for the element derived from its ore, Wolframite The number of protons determines how many electrons surround the nucleus, and it is the arrangement of these electrons that determines most of the chemical behavior of an element. Lets learn come scientific potassium facts. In those cases, the origin of the symbol used is given. A very few elements have symbols which appear to have no relationship with their names. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. Most chemical elements are represented symbolically by two letters, generally the first two in their name.
