In 1876 Dmitri Mendeleev perfected a table to illustrate the elements that are the building blocks of our universe. Mendeleev arranged all the know elements and even predicted properties of undiscovered elements that turned out to be accurate.Today there are 118 know natural and synthesized elements ranging from Hydrogen to Ununoctium. Elements are arranged into two major groups; metals and non metals. From there they can be divided into corresponding sub categories. An element is placed within the table depending on its atomic number, electron configuration and recurring characteristics. Although the periodic table is the most popular representation of elements, there are many alternates, such as the 3D Mendeleev Flower that highlights the relationship between elements in a different way.

Just can't get enough of chemistry? Periodic Coasters are the perfect addition to any geeks home. With Gold, Lithuim, Iron, Neon, Silicon, Krypton and Nitrogen it's difficult to choose a favourite! Each coaster has the atomic number and mass, as well as a witty phrase about the element. Krypton is the 'superhero element' whilst Lithuim with 'keep you lasting for longer'. Now thats elementary!
