Cesium is a Block S, Group 1, Period 6 element. The number of electrons in each of Cesium's shells is 2, 8, 18, 18, 8, 1 and its electronic configuration is [Xe] 6s1. In its elemental form cesium's CAS number is 7440-46-2. The cesium atom has a radius of 265.5.pm and it's Van der Waals radius is 200.pm. Cesium compounds are slightly toxic. Cesium is a member of the alkali group of metals. It is one of three metals that occur as a liquid at room temperature - the others are mercury and gallium. Cesium 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. Cesium is used as an oxygen "getter" in vacuum and electronic tubes and as a component of photoelectric cells. Cesium compounds are considered to be slightly toxic. Atomic clocks use the microwave spectral line emitted by Cesium Isotope 133 for reference. Cesium chloride is an unproven treatment for cancer. Radioactive Cesium 137 is an artificial isotope produced that is an approved radiation source for cancer radiotherapy. Under pressure, Cesium hydride is stiffer than diamond. Laboratories use various cerium compounds for their ability to hydrogenate organic compounds. Cesium was first discovered by Fustov Kirchhoff in 1860. Caesium is named for the vibrant blue lines in its spectrum. The word Caesium originates from the Latin word 'caesisus' meaning "sky blue". See Cesium research below.
Tantalum 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 electronic 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 telecommunications 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.
