Periodic Table Puzzle
The code letters A to Z have been assigned to represent the first 26 representative elements in the
Periodic Table. The letters do not relate to the actual chemical symbols for these elements.
Your challenge is to put the code letters in the correct boxes in the Periodic Table, based on the
properties given below.
