Hunds Rule

Postby Prina Patel 1H » Wed Oct 07, 2015 11:55 pm

I did not learn Hund's Rule in my chemistry class so I am still confused to as to what it is and how to use it effectively? Can someone give me an example of how to use it and what it is exactly?

Hund's rule basically says that due to the repulsive forces between electrons, electrons fill orbitals within a subshell in a specific way: they fill first all available orbitals in that subshell with just one electron, each with parallel spins. Then, only once each available orbital has one electron, the electrons will start to add a second electron with an antiparallel spin to each orbital until all orbitals are full.

Here's a visual aid for Hund's Rule, which may help you understand a bit better (if you're visual learner like I am):
