Questions:
What
is the difference between the two? Why do you think hydrogen is different?
Here I have draw hydrogen with atomic orbitals higher than 1. Is this correct? Why or why not?Slide4

Electron Configurations: Exceptions
When valence d orbitals have electrons and you need to make an positive ion, remove from valence s orbitals first.
Half filled and full filled orbitals are more stable. To get d orbitals to this stability promote electrons from s orbitals
Fs also have a bunch of exceptions, don’t worry about these. If I ask for an electron configuration from the F block, just follow the rules
Question: Why can we be so fluid with our exchange of electrons from the s and d orbitals?
Energy levels are very close to each other!Slide10
