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.
“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).
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 • 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
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. Transition metals
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
Now… • Tape the lanthanides and actinides in a loop coming out of the transition elements where they belong. • Here
