Potassium 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 electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes 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.
Palladium is a Block D, Group 10, Period 5 element. The number of electrons in each of Palladium's shells is 2, 8, 18, 18 and its electronic configuration is [Kr] 4d10. In its elemental form palladium's CAS number is 7440-05-3. The palladium atom has a radius of 137.6.pm and it's Van der Waals radius is 163.pm. Palladium is a member of the palladium group of metals. It is an excellent hydrogenation and dehydrogenation catalyst and available in many Organo-metallic forms for this purpose. It is alloyed with gold, silver, iridium and other palladium group elements and used in jewelry. The metal is used in dentistry, watch making, and in making surgical instruments and electrical contacts. Palladium 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. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below.
Sulfur is a Block P, Group 16, Period 3 element. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electronic configuration is [Ne]3s2 3p4. In its elemental form sulfur's CAS number is 7704-34-9. The sulfur atom has a radius of 100pm and it's Van der Waals radius is 180pm. Sulfur is a crucial element for all life and serves as both fuels and respiratory (oxygen-replacing) materials for simple organisms. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, Epsom salts, and barite. Sulfur, when organically bonded, is a component of all proteins, as the amino acids methionine and cysteine. In organic form, Sulfur is present in the vitamins thiamine and biotin. Sulfur is also a vital part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin.Sulfur is available as compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity). Sulfur has been known since ancient times but was not accepted as an element until 1777. Antoine Lavoisier helped to convince the scientific commuity that sulfus is an element and not a compound. See Sulfur research below.

Sulfur is a Block P, Group 16, Period 3 element. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electronic configuration is [Ne]3s2 3p4. In its elemental form sulfur's CAS number is 7704-34-9. The sulfur atom has a radius of 100pm and it's Van der Waals radius is 180pm. Sulfur is a crucial element for all life and serves as both fuels and respiratory (oxygen-replacing) materials for simple organisms. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, Epsom salts, and barite. Sulfur, when organically bonded, is a component of all proteins, as the amino acids methionine 
and cysteine. In organic form, Sulfur is present in the vitamins thiamine and biotin. Sulfur is also a vital part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin.Sulfur is available as compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity). Sulfur has been known since ancient times but was not accepted as an element until 1777. Antoine Lavoisier helped to convince the scientific commuity that sulfus is an element and not a compound.
