The configuration of Selenium involves setting up a WebDriver instance with desired capabilities, specifying the browser type and version, setting up the path to the driver executable, and configuring any additional desired options. This configuration allows Selenium to automate the chosen browser for web testing.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.

The aufbau principle is a method for determining the electron configuration of an element. It shows how the various orbitals must be filled in correct sequence to show how ionization may occur. For selenium, the correct aufbau sequence is [AR] 4s2 3d10 4p4.
