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.

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

It should look like
