cesium mass number

This chemical element is distinctive for several reasons. Melting point of Caesium is 28,4 °C and its the boiling point is 690 °C. Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. How many electrons does cesium-137 have? It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Mass Percent: Cesium: Cs: 132.90545: 1: 100.000% ... of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. This presents a particular hazard when radioactive cesium-137 contaminates the soil, as it did near Chernobyl.Growing plants require large amounts of potassium, and concentrate it from the soil. The mass of a cesium (Cs, atomic number 55) atom is 2.21×10−25 kg, and its radius is R = 2.65×10−10 m. The mass of the atomic nucleus roughly equals the mass of the whole atom. Atomic Number of Caesium is 55.. Chemical symbol for Caesium is Cs. Density is the mass of a substance that would fill 1 cm 3 at room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Number of protons in Caesium is 55. Round your answer to 1 (one) significant figure. Isotopes Where more than one isotope exists, the value given is the abundance weighted average. Cesium or caesium is a metal with the element symbol Cs and atomic number 55. Atomic weight of Caesium is 132.905452 u or g/mol. Cesium. This is approximately the sum of the number of protons and neutrons in the nucleus. Calculate the fraction of the volume occupied by the nucleus in a cesium atom. Atomic Number of Caesium. In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have. The nuclear density is 2×1017 kg/m3. Relative atomic mass The mass of an atom relative to that of carbon-12. The compounds of cesium are similar to those of potassium. The mass number of the stable form of cesium is 133.
