CHEM 10: Challenge Problem Set 2
1. The reaction below depicts the alpha decay of plutonium-242. Besides helium, identify the other
product of this nuclear decay by specifying the element symbol (E), the mass number (A) and
the atomic number (Z) in the fields provided.
2. The reaction below depicts the beta minus decay (β-) of magnesium. Besides an electron (the
beta particle), identify the other product of this nuclear decay by specifying the element symbol
(E), the mass number (A) and the atomic number (Z) in the fields provided.
