    Balanced Nuclear Equation for the Alpha Emission of Bismuth-210:<\/h3>\n\n\n\n

    [
    \\text{Bi-210} \\rightarrow \\text{He-4} + \\text{Pb-206}
    ]<\/p>\n\n\n\n

    Explanation:<\/h3>\n\n\n\n

    In nuclear decay processes, the nuclide undergoes transformations that involve either the emission of particles or the rearrangement of its components. In the case of alpha decay<\/strong>, an alpha particle (which is composed of 2 protons and 2 neutrons, symbolized as (\\text{He-4})) is emitted from the nucleus of the decaying nuclide.<\/p>\n\n\n\n

      \n
    1. Understanding the elements involved:<\/strong><\/li>\n<\/ol>\n\n\n\n
        \n
      • Bismuth-210<\/strong> ((\\text{Bi-210})) has an atomic number of 83 and a mass number of 210. This means it contains 83 protons and (210 – 83 = 127) neutrons.<\/li>\n\n\n\n
      • The alpha particle<\/strong> ((\\text{He-4})) has an atomic number of 2 and a mass number of 4, representing 2 protons and 2 neutrons.<\/li>\n<\/ul>\n\n\n\n
          \n
        1. Effect of alpha decay on the nucleus:<\/strong><\/li>\n<\/ol>\n\n\n\n
            \n
          • The emission of an alpha particle reduces the atomic number of the original nuclide by 2 and the mass number by 4. Therefore:\n
              \n
            • The atomic number of Bismuth (Bi)<\/strong> decreases from 83 to (83 – 2 = 81).<\/li>\n\n\n\n
            • The mass number decreases from 210 to (210 – 4 = 206).<\/li>\n\n\n\n
            • The resulting product nuclide is Lead-206<\/strong> ((\\text{Pb-206})).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Writing the nuclear equation:<\/strong><\/li>\n<\/ol>\n\n\n\n
                  \n
                • The alpha emission equation can be written as:
                  [
                  \\text{Bi-210} \\rightarrow \\text{He-4} + \\text{Pb-206}
                  ]<\/li>\n\n\n\n
                • This equation balances both the mass numbers and the atomic numbers:\n
                    \n
                  • The mass number on both sides: (210 = 4 + 206).<\/li>\n\n\n\n
                  • The atomic number on both sides: (83 = 2 + 81).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

                    Thus, the correct nuclear equation for the alpha decay of bismuth-210 is (\\text{Bi-210} \\rightarrow \\text{He-4} + \\text{Pb-206})<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
