Homework Problem 3.19

[Krista Mercado 1B]

Give the ground-state electron configuration and number of unpaired electrons expected for each of the following ions:
(a) Sb3
(b) Sn4
How do you find the number of unpaired electrons?

[Mahir_Hasan2C]

We use the electron configuration. We would adjust this due to the charge. Then we draw the spins of the electrons.

[Alma Carrera 3C]

Using the valence electrons, fill out the outermost shell by following Hund's Rule, which says to fill in 1 electron in each orbital first and then start pairing them once each orbital 1 electron. Then you can see how many electrons remain unpaired.
