Manganese Electron Configuration Concepts

The video tutorial by Melissa Maribel addresses a question about determining the number of inner, outer, and valence electrons in a manganese atom. It begins with an introduction to electron configuration, explaining how to locate manganese on the periodic table and write its expanded and abbreviated electron configurations. The tutorial then details how to identify inner, outer, and valence electrons using these configurations. The video concludes with a summary and additional resources for further learning.
