Molecular Crossword Puzzle

by George Barany and Michael Shteyman

This 7x7 puzzle, with an original, rather unusual format, was distributed to the students of an organic chemistry class that I was teaching, as the students were turning in their final exams in December 2005. We thank Jed Fisher and Lloyd Fricker for their astute beta testing of the puzzle.

Instructions:

The "alphabet" to fill in this puzzle consists of the one-letter or two-letter symbols from the Periodic Table of the Elements.

Part of your challenge, once you have worked out each clue answer, is to decide how to parse it to fit into the 7x7 grid. For example, the word "bathes" can be parsed as BA-TH-ES (atomic numbers 56-90-99), B-AT-HE-S (5-85-2-16), or B-AT-H-ES (5-85-1-99)
