Electron Configuration is an app that is a handy tool for those who want to get to know more about the elements and how they are configured. There are two ways to use the app. You can either choose an element from the list or type in one.

To use the app, you need to first select the element you want to know more about. Next, tap on the "Config" button. This will open up a window that will show you the element's configuration. You will see the number of electrons, the energy level, and the number of valence electrons.
