Alright. So here it says, write the full ground state electron configuration and electron orbital diagram for the following element. So we're looking at titanium. Here we're given its atomic number as being 22. So if we come up here, I've already marked off where titanium is. It's right here. So all we have to do is count to it starting with 1s. So we'd say s12, s22, p26, which gives us all 6 of these slots. s32, p36, s42, d32. So that would be my full ground state electron configuration of titanium.

Now, we have to give the electron orbital diagram for the following element. Now typically for electron orbital diagrams, we'd write the condensed electron configuration and then give the electron orbital diagram. So if we're talking about condensed electron configuration, we'd say that the last noble gas that I pass before I get to titanium is argon. So for the condensed, we'd start out with argon. And then we'd say s42d32.

Now, we're gonna say for our electron orbital diagram, our noble gas would fit within these brackets. Then remember, an s sublevel has one electron orbital. And then a d sublevel has 5 electron orbitals. So remember, that's coming from this section here. So that's why we have 5 boxes here because they're part of 3d. Alright. So, we'd totally fill in 4s. It has 2 electrons in it, one spins up, one spins down. And then within 3d we have 2 electrons. Following Hund's rule, we first half fill. So, we have 2 electrons: up, up. And, we stop because we don't have any more electrons. So, this would represent the electron orbital diagram for titanium.

So, it's just what we've seen previously in terms of electron configurations, but now we're paying close attention to our transition metal.

Now that you've seen this example, attempt to do the practice one on your own. Here, you're just asked to write the condensed electron configuration for the cobalt (I) ion. So remember the rules we talked about in terms of charged electron configurations and apply them to this example. I'll give you a huge hint. It's best to write the electron configuration of the neutral form of cobalt first, then that gives you an indication of what to do to write the electron configuration of its ionic form. Once you've done that, come back and see if your answer matches up with mine. Good luck, guys.
