This week's quiz is multiple choice of sorts, but you have to figure out what the choices are. Name the following chemical elements, each of whose symbols is identical to a U.S. state's two-letter postal abbreviation (ignoring capitalization). Give yourself one point each for the chemical element, its symbol, and the matching state. As a super tough bonus question (for six more possible points), which two chemical elements are missing?
