Formerly in natural science, my path changed after a year at Cégep de Valleyfield. Now I am in computer technology and I really like it. Here is my app made for personal work. The goal was to make a periodic table with a portrait and landscape view. Also, when we click on one of the elements, we can see more information about this element and even see a graphical representation of the electronic configuration. (To see it we must click on the electronic configuration in bold). Use the app as you want and feel free to give me feedback!
