Crossword Puzzle: In the 2 × 2 box shown here, each answer must be correct four ways: horizontally, vertically, diagonally, and by itself. Instead of words, use symbols of elements. When the puzzle is complete, the four spaces will contain the over-lapping symbols of 10 elements. There is only one correct solution. Horizontal 1–2: two-letter symbol for a metal used in ancient times 3–4: two-letter symbol for a metal that burns in air and is found in Croup 5A Vertical 1–3: two-letter symbol for a metalloid 2–4: two-letter symbol for a metal used in U.S. coins Single squares: All one-letter symbols 1: a colorful non-metal 2: colorless, gaseous non-metal 3: an element that makes fireworks green 4: an element that has medicinal uses Diagonal 1-4: two-letter symbol for an element used in electronics 2-3: two-letter symbol for a metal used with Zr to make wires for superconducting magnets This puzzle first appeared in Chemical & Engineering News , p. 86, December 14, 1987 (submitted by S. J. Cyvin) and in Chem Matters , October 1988.
