SpletThis holds true for the mass numbers as well. The atomic number of the product must be: 92 − 40 = 52 The mass number of the product must be: 235 + 1 − 97 − 2 = 137 3) The element with an atomic number of 52 is Te. So, the other product must be: 137/52 Te Note: sometimes, the space is not used, as in 137/52Te Splet9 The notation for the nuclide 137 55 Cs gives infor-mation about (1) mass number, only (2) atomic number, only (3) both mass number and atomic number (4) neither mass number nor atomic number 10 Which pair represents two forms of an element in the same phase at STP but with different structures and different properties?
Splet15. feb. 2024 · Radionuclide Basics: Cobalt-60. Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. Cobalt is similar to iron and nickel in its properties and can be magnetized like iron. The most common radioactive. isotope. of cobalt is cobalt-60 (Co-60). Cobalt-60 is a byproduct of nuclear reactor operations. SpletWrite the following isotopes in nuclide notation (e.g., _6 ^14 C): (a) oxygen-14 (b) copper-70 (c) tantalum-175 (d) francium-217.
