Electron Principles

Postby Gabriel Ordonez 2K » Sun Oct 20, 2019 10:21 pm

Can someone please explain to a greater depth the following: Hund’s Rule, Pauli Exclusion Principle, and Aufbau Principle? Thank you in advance.

What exactly would you be looking for? The general meaning and use of these equations? I would love to help if you specified! :D

Absolutely! Here's a great resource that will help you understand electron configurations and those topics in particular in a bit more depth. https://chem.libretexts.org/Bookshelves/Inorganic_Chemistry/Map%3A_Inorganic_Chemistry_(Miessler%2C_Fischer%2C_Tarr)/2%3A_Atomic_Structure/2.2%3A_The_Schr%C3%B6dinger_equation%2C_particle_in_a_box%2C_and_atomic_wavefunctions/2.2.3%3A_Aufbau_Principle
Essentially, we are really interested in the nature of an atom's electrons when the atom is at it's lowest energy, or ground state. This gives us a basis to start considerations into what electrons do when they're excited from their ground state. The 3 principles you mentioned are the guidelines on how we build up these ground state electron diagrams, and should be well understood.

Can anyone summarize this for me?
