Vertically (rows), elements are arranged in 18 groups, with each group ordered based on electron quantity within the atoms of the elements. Horizontally (columns), elements are organized based on the level of their electron ground state energy. Next, we see the elements arranged in periods and groups (columns and rows). The last element, Oganesson, has an atomic number of 118. Hydrogen lands in the first spot because it has only one proton per hydrogen atom. 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!
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.
