Let’s Talk About the Periodic Table
The periodic table has a long, rich history. It is a tabular arrangement of the chemical elements, organized based on their atomic number, electron configurations, and chemical properties. It was first proposed by a Russian chemist named Dmitri Mendeleev in 1869, although the concept of organizing elements based on their properties was not entirely new.
Mendeleev’s contribution was to organize the elements according to their atomic weight, while also leaving gaps for undiscovered elements that he predicted based on the periodicity of the table. This prediction was later confirmed with the discovery of gallium, scandium, and germanium, which had properties that matched Mendeleev’s predictions. 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.
The periodic table has undergone numerous revisions and refinements since its inception, with the modern version organized based on the number of protons in an element’s nucleus (i.e., its atomic number). It remains a fundamental tool in chemistry, helping scientists predict the properties and behavior of elements, and enabling them to design new materials and compounds.
As you can probably tell, the table has come a long way since then. ChemTalk is committed to bringing you the most beautiful, elegant periodic table in the world. Because of this, we would like to introduce our new interactive periodic table, the ultimate tool for exploring the magical world of chemistry! We’ve taken the traditional periodic table and transformed it into an immersive, interactive experience that will engage and inspire chemists and non-chemists alike. With just a few clicks, you can explore the properties and characteristics of each element, learn about its uses and applications, and even see periodic trends in action. Whether you’re a seasoned chemist or just starting your journey, our interactive periodic table is the perfect place to start!
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 due to the f subshell only holding 14 electrons. But let’s not talk about thorium!
Learning About Periodic Table Trends
There are many trends in the periodic table, and you can learn all about them in our fabulous periodic trends article. Take a look at our periodic table and you can visualize the trends of properties like atomic radius, electronegativity, and ionization energy.
