The INTERNET Database of Periodic Tables
There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).

Zigzag Periodic Table
In this periodic table we can see that the elements are arranged in a different way. Hydrogen is placed in between (and above) fluorine and lithium. This is because there is an issue on the placement of hydrogen as it has the properties of both alkali metals and halogens.
How to read the Zigzag periodic table
For periods (1), (2B), (3B) etc. read from right to left.
For periods (2A), (3A), (4A) etc. read from left to rightThe arrows will guide you through the periodic table:

- Periodic Trends Atomic Radius- When moving opposite to the zigzag line in a particular period, the atomic radius of the elements increase.
- Metallic Character- Metallic Character decreases when moving along the zigzag line in a particular period.
- Ionization Energy- When moving along the zigzag line in a particular period, the ionization energy increases. Electron Affinity- Electron Affinity increases when moving along the zigzag line in a particular period.
