In this video we will write the electron configuration for S 2-, the Sulfide ion. We’ll also look at why Sulfur forms 2- ion and how the electron configuration for S2- is the same as the Nobel gas Argon. • To begin with, Sulfur (S) has an electronic configuration of 1s2 2s2 2p6 3s2 3p4 . To learn more about writing electron configurations see: • • Introduction to Writing Electron Configurations: • Introduction to Electron Configurations • • Electron Configurations Chart: • Using the Electron Configuration Chart • • Writing Electron Configs Using only the Periodic Table: • Writing Electron Configurations Using... • When Sulfur forms an ion it gains two valence electrons Since electrons are negative, gaining two electrons results in S having a 2- charge. • To write the electron config all we have to do is add two electrons to the configuration for S. That leaves us with: • 1s2 2s2 2p6 • And that is the electron configuration for S 2- , the Sulfide ion.
