Problem 6.1 Write out the electronic configuration of the ground state for magnesium Mg (Z=12). Problem 6.2
is a radioactive gas that can be trapped in the basements of homes, and its
presence in high concentrations is a known health hazard. Radon has a half-life of 3.83 days. A gas sample contains 4.00 × 108 radon atoms initially. How many atoms will remain after 14.0 days have passed if no more radon leaks in? What is the activity of the radon sample after 14.0 days? How long before 99% of the sample has decayed?
