Practice Problem: Radioactive Half-Life
All radioactive nuclei have a particular half-life, or the time it takes for their concentration to be cut in half. Given the half-life of one such nuclide, can you find the decay constant, and the fraction of nuclei left over after a...

8 Lesser-Known, Useful Elements
There are 118 elements on the periodic table, but it seems like only a handful of them get any attention. But just because you haven't heard of an element doesn't mean that it isn't a vital part of everyday life. Hosted by: Michael...

Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...
