Problem
An unknown isotope transforms into another whose mass number is 8 less and atomic number is 4 less than the original. Which sequence of two radioactive decays is most consistent with this net change?
(a) One α decay followed by one β− decay
(b) Two successive α decays
(c) Four successive β− decays
(d) One β− decay followed by one α decay
