The INTERNET Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.
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 right
The 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.
