First, each element is arranged in numerical order of its atomic number. The arrangement of the periodic table is very important in our understanding of it. How is the periodic table of the elements arranged? It’s no wonder we see this fascinating table all over the science world! Element type (alkali metals, basic metals, semimetals, etc.).The atomic number (the number of protons in the nucleus of the element).I like to think of the periodic table as a chemistry “cheat sheet.” It offers a wealth of knowledge for each of the 118 elements, including: This original version contained just 63 elements, and that number has grown to 118 today! If a new element is ever discovered, it will be added to the current 118 elements on the table. It was first professionally published in 1869 by Russian chemist and inventor Dmitri Mendeleev. The periodic table arranges all known chemical elements into a succinct chart for easier identification. So, for all of you high schoolers out there, we’re here to help you better understand this complicated-looking table that willl help you make sense of chemistry.įor starters, let’s take it back to the basics. Most students are introduced to the periodic table at a fairly young age, and it is often taught all the way through high school graduation. What’s in every science book, every science lab, and every science lover’s brain? It’s the periodic table of elements! The majority of us can identify this fascinating chart when we see it, but many don’t know how to actually read and understand the information displayed on the periodic table.
