In this video I explain the topic of quantum numbers in connection with the orbital model. Quantum numbers include the principal quantum number, secondary quantum number, magnetic quantum number and spin quantum number, which describe the electrons in the orbital model in more detail. I also address the topic of electron configuration. Image sources: Geek3, https://commons.wikimedia.org/wiki/Fi... , "F orbitals m", https://creativecommons.org/licenses/...
