Electron Configuration and Atomic Structure

This video tutorial from MooMooMath and Science covers the electron configuration of ruthenium, highlighting its exception to the normal rules. The instructor uses the diagonal rule to draw an orbital chart, explaining the capacity of S, P, D, and F orbitals. The video details the step-by-step process of filling orbitals for ruthenium, noting its stability at 5s1 4d7 instead of the expected 5s2 4d6. The tutorial concludes with a brief promotion of the channel's daily math and science content.
