Periodic Table Arrangement

Typewriter arrangement § The periodic table is made to fit on a piece of paper so it can be easily read and printed. § However this leaves several gaps that can break the flow of the periodic table in the reader’s eyes.

Normal Arrangement

“Long” Arrangement § Lanthanides and Actinides are supposed to be in there like this but it makes it less printable and readable. § It also adds a huge disconnect between Beryllium and Boron (and others).

Spiral Arrangement

Alexander Arrangement of the Elements § This connects the normal periodic table to the spiral arrangement by making a 3 dimensional model. § All it takes is some scissors and tape.

How to…Cut here

How to § Roll the pieces you have face out around a pen or pencil so that it coils easily when you release it. § Fold creases on the edges of the transition metals marked by the dotted line

Now… § Tape the lanthanides and actinides in a loop coming out of the transition elements where they belong. § Here

Cont. § Push the transition metals so that they form a loop face out and tape group 2 next to group 13. § In this picture the transition metals would be a loop flopping out of the screen. H Be Na Mg K Ca Rb Sr Cs Ba Fr Ra Transition metals Li

AAE § Now fold the Noble Gases around so that they connect to the Alkali Metals. § Connect He to Li (2 -3) § Ne to Na (10 -11) and so forth § Here is an overhead view of what you should have Main group elements Transition metals Lanthanide and actinide series
