    Answer:

    a): The name of the product nuclide is lead-214

    b): The symbol of the product nuclide is Pb-218

    Explanation:

    There are three types of decay processes:

    • Alpha decay
    • Beta decay
    • Gamma decay

    Alpha decay is the decay process that happens when a heavy nucleus decays into a light nucleus with the release of an alpha particle. This alpha particle carries a charge of +2 units and has a mass of 4 units. It is also known as the helium nucleus. The general equation for this decay process is:

    _Z^A\textrm{X} → _{Z-2}^{A-4}\textrm{Y}+_2^4\alpha

    The nuclear equation for the alpha decay of Po-218 follows:

    _{84}^{218}\textrm{Po}\rightarrow _{82}^{214}\textrm{Pb}+_2^4\alpha

    Hence, the name of the product nuclide is lead-214 and the symbol is Pb-218.
