Potassium(K) atomic and molecular weight, atomic number and elemental symbolPotassium is a Block S, Group 1, Period 4 element. The number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is not toxic. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and Potassium Bohr Modelelectropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal Elemental Potassiumdecomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium research below.

Tantalum(Ta) atomic and molecular weight, atomic number and elemental symbolTantalum is a Block D, Group 5, Period 6 element. The number of electrons in each of Tantalum's shells is 2, 8, 18, 32, 11, 2 and its electronic configuration is [Xe] 4f14 5d3 6s2. In its elemental form tantalum's CAS number is 7440-25-7. The tantalum atom has a radius of 143.pm and it's Van der Waals radius is 200.pm. Tantalum is not toxic. Tantalum has a number of interesting properties that make it particularly useful in Elemental Tantalumelectronic applications. Tantalum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It has the third highest melting point, surpassed only by rhenium and tungsten, yet it is highly conductive to heat and electricity. This has made it the material of choice for electronic capacitors for most Tantalum Bohr Modeltelecommunications and hand held electronics equipment, such as cell phones, laptop computers and pagers. Tantalum compounds, such as the oxide and chloride, are the basis for di-electric coatings. Tantalum is added to glass for its high refractive index. It has various applications in nuclear energy. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology. See Tantalum research below. See Tantalum research below.
