<p>Periodic Table Puzzle</p><p>The object of this puzzle is to use the periodic properties of the elements to fill in the following chart. The code letters A to Z have been assigned to the first 26 representative elements in the periodic table. The code letters do not represent certain chemical symbols, that is, C may not be carbon, nor have the letters been assigned in alphabetical order.</p><p>Your task is to arrange these letters in the proper location in the periodic chart. To do this, use the clues given pertaining to certain members of each group. Clues: The following elements belong together in groups: WXYZ, STUV, ABC, DEF, GHI, JKL, MNO, and PQR. 1. Element M is not the smallest in its group. 2. Elements L & E are in the same period. 3. The atomic radius P is smaller than element R. 4. Element T has the lowest ionization energy in its group. 5. Element W is more reactive than element A and element A is more reactive than element D. All three elements are in the same period. 6. The atomic radius of H is smaller than element I. 7. Element B is the least reactive alkaline earth metal. 8. Element K has 5 valence electrons. 9. L has a lower ionization energy than K. 10. Element Q is the most reactive halogen. 11. The atomic number of element V is one more than element P. 12. Element J is the most reactive element in its group. 13. Elements C and N are from the same period and react to form CN. 14. Element O forms a -2 ion. 15. Element Z is the most reactive metal in its period. 16. The atomic number of Z is 16 more than the atomic number of Y.</p><p>17. Element E reacts with element P to form the ionic compound EP3. 18. Element U has the smallest radius in its period, but not in its group. 19. Element G has the highest ionization energy in its group. The following Periodic Table shows only groups 1, 2, and 13-18. The transition metals have been omitted. The atomic numbers are shown.</p><p>1 2</p><p>3 4 5 6 7 8 9 10</p><p>Tran 11 12 sitio 13 14 15 16 17 18 n Meta 19 20 ls 31 32 33 34 35 36 Answers to Periodic Table Logic Puzzle</p><p>Going down the groups:</p><p>Group I: X, Y, W, Z Group II: B, A, C Group III: F, D, E Group IV: G, H, I Group V: J, K, L Group VI: O, M, N Group VII: Q, P, R Group VIII: S, U, V, T X S Y B F G J O Q U Tran sitio n W A Meta D H K M P V ls Z C E I L N R T</p>
