Alexander Arrangement of Elements Periodic Table
three dimensional Sketch of the ElementBook

This activity will allow construction of a rough three-dimensional sketch of the three dee periodic table called ElementBook without the need to see. The actual A A E ElementBook package will have a raised grid of element data boxes containing braille atomic numbers and element letter symbols, as well as reference booklets for element names, properties, valences, etc.

Needed: An eight and a half by eleven inch a sheet of printer paper; ability to fold paper neatly in half and burnish it (with flat of fingernail while folding back and forth) and tear it; and at least three regular wire paper clips.

ElementBook Construction

Fold the sheet in half the long way, and half again to make 4 sections.
Open and fold the other way, in half, and half again to make 16 sections.
Open and fold along a crease nearest a long edge.
Burnish firmly along fold and tear off these 4 sections and set aside for booklet.
The cut (not torn) edge of the larger part is the bottom - put it toward you.
Fold the sheet in half the short way, right side over left.
Fold the bottom sections up at the crease.
Burnish that fold firmly from the previous folded edge (right side) to the vertical crease.
Bring the bottom sections back down.
Tear the paper from the fold edge along the burnished fold to the crease.
Bring the right and left sides together, adjusting folds so front sides of the upper sections will meet and the back sides of the lower sections will meet.
Paperclip the top or fold of the protruding two bottom sections together.
Swing the top two sections to the left and paperclip them at the top behind those three sections.
Fold and burnish all vertical folds so they fold freely in both directions.
Tear the paper from the top down along the center crease to the first horizontal crease.
Fold the right upper section down behind the middle section and paperclip.
Fold the left (tall) section in half vertically to make a score, and return to flat.
------------
The result is a construction with 6 vertical surfaces hinged together in a sketch (proportions less than approximate) of the form of the Alexander Arrangement of Elements and the ElementBook.
The tallest segment will have s-block elements on the front and most of the p-block elements on the back. The shortest segment, hinged near the bottom of the s-block, is the f-block, with half the elements on one side and half on the flip side.
Hinged to those (and to the s-block above) is the d-block, half the elements on one side and half on the flip side.
That side hinges to the p-block, where the first four of its six element columns are found.
The remaining two columns are on the flip side, adjacent to the s-block.
In all periods, the p-block element boxes slant downward one elementŐs height between the d- and s-blocks, connecting the last element of one period to the first of the next, perfecting the continuity of MendeleevŐs Line.
------------
The consecutive line of elements will start in the first period on the tall segment, wrapping to the back for 2 more periods. At the 4th and 5th periods the element line will continue onto the middle height segment, wrapping to the rear, past the fold to the p-block, wrapping again to the s-block
The later periods include the f-block elements between the s-block and the d-block.

DataBooklet Construction

Locate the 4 sections removed earlier.
Fold the short way in half, half again, and in half once more.
Open and alter folds to alternate back and forward (accordion folds).
Lay down with end section edges up.
Apply glue along entire length.
Bring right and left ends together so all sections, in pairs, are glued together.

This forms a booklet with 8 pages - for supplementary data referenced from the ElementBook. Information will be printed sideways, parallel to the folds.

What is the ElementBook periodic table?
The ElementBook periodic table is a chart with raised Braille data and lines in a grid made up of over 100 element data boxes in a set sequence, ordered in a continuous row from left to right by the number of protons in the nucleus according to the Periodic Law.
These element data boxes are grouped in 4 blocks according to certain properties.
They are in periods, 1 to 8, depending on the number of shells of electrons.
They are grouped in columns according to their valences and other properties.
Many (single or multiple) columns show such strongly related property relationships among the elements that they are called 'families'.

The information in an element data box of the ElementBook is the atomic number (top left, 2 or 3 digits) and the element symbol (bottom left, 1 or 2 letters, both lower case).
The information on the most basic reference booklet is the atomic number, followed by the symbol, followed by the name of the element. These last two have no scientific meaning, and are merely for reference purposes. The list is in the order of the atomic numbers, one element under the previous one, which permits back and forth reference with the ElementBook.
Separate reference booklets may be desirable to portray valences and property trends - especially in the main groups - the s- and p-blocks, and might be lists or in a grid of some fashion.

Q. Why does one use a periodic table?
A. To learn something about an element that is unknown.

Q. What information does one already have that bears upon an intended use?
A. At least one item, be it atomic number, symbol, name, valence, or property.

Q. Why does one use the ElementBook instead of the normal periodic table?
A. Lack of vision does not permit use of a printed periodic table.

Q. Why use a periodic table at all?
A. There are multiple reasons, depending both on what one knows and what one needs to know. My current understanding of some procedures for use of the proposed ElementBook product package follows:

1.
With only an atomic number, and to find an element's name or symbol, use the the basic booklet, reading from top to bottom.

2.
With only an atomic number, and to find an element's position on the periodic table:
Find column one of the periodic table grid - on the tallest page, the second column to the left of the hinge.
Read (finger on the braille) up from the bottom row (period 8) and find the atomic number ( # ) above that which you seek. Subtract from 8 when passing by each box to identify the period.
Read up to see the # of the element above. Subtract 1 more from the period number.
You will be reading to the right from there if the sought # is less than half way to the # of the element below, or to the left if closer to the # below.
Read # across, turning pages while keeping finger within the horizontal lines of the top and bottom of the element data boxes of that period until you locate the sought number.
If you have gone to the left, subtract 1 from the period number. (You will notice that the boxes ramp up in this, the p-block.)
While traversing the period be especially careful to stay in the same period when going around an outside corner.
When arriving at the box with the sought #, by reading up and down, you can learn what elements comprise the rest of the family, who are the neighbors right and left, and at the bottom find the column number.
The shape of the page and number of boxes will tell you the block, as the f-block is 7 wide and 2 high, the d-block is 5 wide and 4 high, the s-block is at least 1 or 2 wide 7 or 8 high and just to the left of the hinge, and the p-block (6 wide and 6 or 7 high) starts on the same plane as the s-block, to the right of the hinge and around to the back, ending at the start of the s-block.

3.
With only an element name, and to find the element's position on the periodic table, you will have to first consult the basic booklet, reading from top to bottom. A good search first shortcut might be to read down the list of symbols, as most of them start with the same letter as the element name. Failing that, read down the initial letter of the element names and check those with a match to what you have. Then look left for the # and follow procedure 2.

4.
With only an element symbol, and to find the element's position on the periodic table, use procedure 3.

5.
When the block is also known you might go directly to the block and scan back and forth for the data you have.
