    Lead-205 (Pb-205)

    Explanation:

    We are given;

    An atom of Po-209

    We are supposed to identify its product after an alpha decay;

    Polonium-209 has a mass number of 209 and an atomic number of 84. When an element undergoes an alpha decay, the mass number decreases by 4 while the atomic number decreases by 2. Therefore, when Po-209 undergoes alpha decay it results to the formation of a product with a mass number of 205 and atomic number of 82. The product from this decay is Pb-205, because Pb-205 has a mass number of 205 and atomic number 82. The equation for the decay is;

    ²⁰⁹₈₄Po → ²⁰⁵₈₂Pb + ⁴₂He

    Note; An alpha particle is represented by a helium nucleus, ⁴₂He.
