Electron Configuration and Nickel Ions

This video tutorial explains how to write the electron configuration for nickel and its ions, Ni2+ and Ni3+. It begins with an introduction to electron configuration, followed by a detailed step-by-step guide to writing the configuration for neutral nickel. The video then covers the condensed notation and explains how ionization affects the electron configuration of nickel ions. The tutorial concludes with a summary of the electron configurations for nickel and its ions.
