This year we celebrate the International Year of the Periodic Table of Chemical Elements – in honor of Dmitri Mendeleev who published his approach to sorting chemical elements into groups and periods 150 years ago. In the meantime, many new elements have been discovered and added to the periodic table – comprising 118 elements as of today. It certainly has become one of the key concepts that come to mind when people think of chemistry.
Whether you need to look up ionization energies, electron configurations, or if you are just after some fun facts on your favorite chemical element: the interactive Periodic Table by the Royal Society of Chemistry is worth a visit.
Click on the elements and you’ll find all physical data, isotopes, applications, history, as well as further interesting resources like podcast videos on each entry!
For mobile devices there are even apps available to download from the App Store or Google Play.
Have you found your favorite chemical element yet?
