Periodic Table Mystery By Chuck Roser, Retired Chemistry Instructor North Carolina School of Science and Mathematics National Science Education Standards Grades 9–12 (HU2—Evidence and Models, HB2—Structure and Properties of Matter) Objective Using coded symbols for the main group elements in the first 4 periods of the periodic table, students will generate a periodic table from pertinent clues. Introduction The periodic table used today is a product of the 1st periodic table published by Russian chemist Dmitri Mendeleev in l869.
