I used two file folders and hooked them together at the top with a giant paper clip. Attach two of the periodic tables in with that paper clip as well. Then lay the other two periodic tables down on the table in the folder. If you want it to be more permanent you can glue them on...

Since CHEMMEND,an existing physical card game, was found to assist with learningthe periodic table, we explore the potential of E-CHEMMEND, a digitalversion of the game as an aid to memorize the group and period numbersof the elements. E-CHEMMEND is a single-player serious game to ...
A Central Position for Hydrogen in the Periodic Table Many years ago in the now classic textbook cllege Chemistry (W.H.Freeman&Co.,1954),Linus Pauling placed the symbols for hydrogne and helium at the head and center of the periodic table with arrows indicating the chemical relationships of....
General Trends of the Periodic Table Atoms are arranged by their atomic numbers. Fr is the most active Metal (botton left) – circle it F is the most active Nonmetal (top right, but not a noble gas)– circle it Size increases downward and to the left ...

Regarding the first goal, we are now glad to fill the blank space of Zn(II) in this “periodic table” by describing the syntheses, structures, and spectroscopic characterization of the first Zn(II) complexes; we also support our experimental data by theoretical calculations, with emphasis on ...
Groups in the Periodic Table of Elements Click on an element to read about the chemical and physical properties of thegroupto which that element belongs. Alkali Metals Less dense than other metals One loosely bound valence electron Highly reactive, with reactivity increasing moving down the group ...

group B can have multivalent elements. The number itself is the the number it is given when you count left to right on the Table. With representative metals, the number also tells you the number of valence electrons elements in that row have so...1a has 1 electron, 2a has 2, 3a has...
