2022: ☢️ Electron Configuration of Selenium (Se) [Complete, Abbreviated, Uses ...

Electrons have a specific form of distribution (or configuration) in every atom, even Selenium. Some are hard to memorise (or predict), so what is the electron configuration of an atom of Se?

In the case of Selenium the abbreviated electron configuration is  [Ar] 3d10 4s2 4p4. Nevertheless, check the complete configuration and other interesting facts about Selenium that most people don't know.

Selenium Overview

Selenium Complete Electron Configuration
