Many people think that elements can be arranged in only one type of Table. But there are several different Table arrangements of elements.

The following slides will show you several different ways that the elements can be organized. Some tables are arranged according to a particular property of the atoms of elements and some are arranged to show a particular relationship.

The next slide is the Standard Periodic Table. It is arranged according to Increasing Atomic Number. In this arrangement the elements fall into groups that have similar properties. This arrangement also serves as a map of the electron structure of the elements. The principal energy levels correspond to the periods (horizontal rows) of the Table and the various sublevels (s, p, d, f) correspond to the groups (columns) of elements

Standard Periodic Table

This is the Extended Standard Periodic Table. It is also arranged according to Increasing Atomic Number. The elements fall into groups that have similar properties, but we can see how the Lanthanide and Actinide series of elements fit into the Standard Periodic Table. A common question from Students about the Standard Periodic Table is, “Why is the Lanthanide and Actinide series separated from the rest of the Table?” The answer is simply one of efficiency of both economics and space. Less paper to produce a larger table.

Extended Standard Periodic Table

The next slide is the Bayley Pyramid Table. It is arranged according to Increasing Atomic Number as well. However, it is arranged in a Hierarchy (showing the elements with the smallest atomic numbers at the top) and emphasizes the Continuity of the periods. Elemental groups with similar properties have the same color and are connected by Black Lines between the levels. This design was common before the present design of the Standard Periodic Table.

Bayley Pyramid Table

This Table is called the A/B Octet Form Table. It is a modern version of an earlier arrangement of Elements. Elements are arranged according to Increasing Atomic Number. The usefulness of the table is that elements listed in an individual vertical column tend to have the same chemical behavior.

A/B Octet Form Table

The next table is called the Energy Matrix Table. It is arranged according to the electron filling patterns of the atoms of each element. The Four Quantum Numbers are given in the table. The Principal Quantum Number, “N” appears at the top of each level. The Quantum Numbers “L” is indicated by the different colors. The Magnetic Quantum Number, “M” appears next to the element that has those levels. Spin Quantum Number “S” is determined by dividing each panel in half horizontally. The bottom is negative and the top is positive.

Energy Matrix Table

This Table is called the Electron Position Form Table. It is not really a periodic table but instead shows the position of each electron according to increasing Atomic Number of the element that may contain that electron. An example of how the table works: If you want to know the electron configuration of Sodium, find electrons 1 to 11. This gives the general location of the 11electrons of the Sodium atom around the nucleus of Sodium atom.

Electron Position Form Table

The tables shown in this slide show come from a freeware/shareware program called Integral Scientist Periodic Table. You can download the program and install it on your computer. The program is fully functional. You do not have to register the program unless you absolutely cannot wait 10 seconds for the “Begin” button to show up on the registration screen. The program serves as a good reference and source for numerical data on a variety of properties for all of the elements in the periodic table. The presentation of the information and graphs are very colorful and easy to follow. The Download Link in Chapter 5 of Module # 2 will give you more information on downloading and installing the program.
