![]() The cost of the metal may range between $38 and $40 per gram. As cesium ions can be ionized and have a high mass, they may be used as a propellant in ion engines of spaceships.When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. Both the melting and boiling points decrease down the group. The nuclear explosion of uranium produces the two isotopes, Cs-134 and Cs-137. The figure above shows melting and boiling points of the Group 1 elements.Eye contamination or spillage over the skin can cause extreme irritation and inflammation. Īccidental ingestion can affect the liver, intestine, and kidneys. ![]() Cesium vapour magnetometer is used in the measurement of earth’s magnetic field.Caesium fluoride can be used in organic synthesis as a source of the fluoride anion. 17 Its compounds burn with a blue 18 19 or violet 19 colour. note 3 16 In addition, the metal has a rather low boiling point, 641 C (1,186 F), the lowest of all metals other than mercury. Cesium-137 implants have been used in some clinical trials to carry out radiation therapy of breast cancer. Caesium fluoride or cesium fluoride is an inorganic compound with the formula CsF and it is a hygroscopic white salt. Mercury is the only stable elemental metal with a known melting point lower than caesium. In some animal studies, the quantity of the element had been increased to raise the pH of the tumor cells and kill them. Seed implants made from Cs have been used as a part of brachytherapy for treatment of prostate cancer.The element, when combined with oxygen, acts as a getter to remove trace gases and other impurities from vacuum tubes. ![]() Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 ☌, which makes it one of only five elemental metals that are liquid at or near room temperature. Physical Properties of Cesium Atomic Mass Average: 132.9054 Boiling Point: 944K 671C 1240F Coefficient of lineal thermal expansion/K-1: 97E Conductivity. Sections below cover the trends in atomic radius, first ionization energy, electronegativity, melting and boiling points, and density. It plays the role of a catalyst in the hydrogenation of some organic compounds. Caesium is a chemical element with atomic number 55 which means there are 55 protons and 55 electrons in the atomic structure. This page discusses the trends in some atomic and physical properties of the Group 1 elements - lithium, sodium, potassium, rubidium and cesium. ![]() It has a melting point of 29.5 degrees Celsius and a boiling point of 844 degrees Celsius.
