Polonium-208 is one of the emitters studied by Marie Curie. Write the equation for the α decay of polonium-208, and identify the element formed.
ANALYSIS Look up the atomic number of polonium (84) in the periodic table, and write the known part of the nuclear equation, using the standard symbol for polonium-208:

^{208}_{84}Po \longrightarrow ^{4}_{2}He + \pmb{?}

Then calculate the mass number and atomic number of the product element, and write the final equation.
