2.53 Predict how many unpaired electrons...

Postby 904837647 » Wed Oct 24, 2018 4:27 pm

For problem 23 in chapter 2, after writing the ground-state electron configuration for each element it asks us to predict the number of unpaired electrons. How exactly do we know which ones will be unpaired?

If you draw the Aufbau diagram it should be clear which electrons are unpaired if you follow the Pauli exclusion principle and Hund's rule.

Unpaired electrons are any electrons that don't have a another electron (with opposite spin) in their orbital. Draw out the Aufbau diagrams for each element using the rules from lecture and you'll be able to see which electrons don't have a buddy!
