Bismuth keeps some bad company. One element to the left is lead,  notable for causing the most important environmental illness existing today. To the right is polonium, a deadly radioactive poison used in genocide. In between sits the completely nontoxic pretty-in-pink bismuth, the active ingredient in Pepto-Bismol, which we pull from drug store shelves to sooteh our queasy tummies. Makes me think a good game of musical chairs on the periodic chart is in order so the good guys can avoid hanging out with the bad.
