Let’s Talk About the Periodic Table
The periodic table has a long, rich history. Dmitri Mendeleev is credited with creating the modern version of the periodic table.
This is our new design for the modern periodic table:
Here’s the first periodic table that Mendeleev published in 1879.
Can you see where Mendeleev predicted gallium? He was literally ahead of his time.
As you can see, the table has come a long way since then. ChemTalk is committed to bringing you the most beautiful, elegant periodic table in the world. Try hovering or clicking over different parts of the table and see what happens!
Leave Feedback and Win Something Amazing!
If you have any suggestions or features that you would like added to our new periodic table, please don’t hesitate to drop us a note. You can win an element of your choice or a beaker set! Simply visit our “Free Element Giveaway”, and in the feedback box include one feature or piece of information that you would like added to our periodic table. Win elements like gold, gallium or sodium!
14 or 15 elements in the f-block?
In our table, we’ve included 15 elements in the “f-block” sections, which are the lanthanides and the actinides. That is also what the IUPAC periodic table uses. However, there is some debate about this, and some chemists feel that there should only be 14 elements in the f-block, because the f subshell only holds 14 electrons. But let’s not talk about thorium.
Learning about Periodic Table Trends
There are many trends in the periodic table, you can learn all about them in our fabulous periodic trends article. We’ll be updating our table soon so you can visualize the trends of properties like atomic/ionic radius, electronegativity, and first ionization energy, Stay tuned!
