A beautiful, and free, app that provides details and glorious 3D images of (almost) every element.
There is a page of information about each element, along with images of how it is used and even how to pronounce its name.
I have just learned that Niobium is named after Niobe the daughter of Tantalus, and the element Tantalum appears just below it in the periodic table. Useful information, possibly not – but fascinating nevertheless. 😊
For the true geeks it also provides data on electron shells, crystal structures, along with of course, melting points, blowing points etc. It also usefully gives background information what each of these data mean and how they are calculated or measured.
All this does come at a price though, although cost free, it is almost 2GB.
You can fid the app here.
