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.

Platinum(Pt) atomic and molecular weight, atomic number and elemental symbolPlatinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f14 5d9 6s1. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and it's Van derWaals radius is 172.pm. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does Elemental Platinumnot oxidize in air at anyPlatinum Bohr Model temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum 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. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below. Platinum compounds have application in medicine. Platinum 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.
