Let’s Speak Concerning the Periodic Desk
The periodic desk has an extended, wealthy historical past. Dmitri Mendeleev is credit score with creating the trendy model of the periodic desk.
That is our new design for the trendy periodic desk:
Right here’s the primary periodic desk that Mendeleev revealed in 1879.
Are you able to see the place Mendeleev predicted gallium? He was actually forward of his time.
As you possibly can see, the desk has come a great distance since then. ChemTalk is dedicated to bringing you probably the most lovely, elegant periodic desk on this planet. Strive hovering or clicking over totally different elements of the desk and see what occurs!

Merely go to our “Free Component Giveaway” , and within the suggestions field embrace one characteristic or piece of data that you prefer to added to our periodic desk. Win parts like gold, gallium or sodium!
14 or 15 parts within the f-block?
In our desk, we’ve included 15 parts within the “f-block” sections, that are the lanthanides and the actinides. That can be what the IUPAC periodic desk makes use of. Nevertheless, there may be some debate about this, and a few chemists really feel that there ought to solely be 14 parts within the f-block, as a result of the f subshell solely holds 14 electrons. However let’s not discuss thorium.
Studying about Periodic Desk Traits
There are various tendencies within the periodic desk, you possibly can be taught all about them in our fabulous periodic tendencies article. We’ll be updating our desk quickly so you possibly can visualize the tendencies of properties like atomic / ionic radius, electronegativity, and first ionization power, Keep tuned!
