00:01 Okay, so when we're writing, i'm going to write down the elements that we are considering here.

00:09 I should have left myself a little bit more room.

00:22 Okay, so these are the elements that we're considering.

00:25 And we're doing electron configurations.

00:35 You fill sublevels, if they're partially filled, you write it last, identify the last, by finding the element, determining which block it is, and the sublevel.

00:45 Identify the last occupied sublevel.

00:53 Identify the last occupied sublevel for each of these.

01:07 Identify the last, and then you're going to drag these, and my options will be, i'm just going to write these down here.

01:14 We can pick 3s, 3p, 3d, 4s, 4f, 5p, and 5d.

01:28 Those are the options i can see.

01:30 So i'm just going to pull up a periodic table here, see where everything is.

01:43 P table, the one we all use.

01:51 And let's go into a red, and make it a red.

01:57 So platinum is down here in the 5d sublevel.

02:02 Was that one of them? yes.

02:07 Platinum is, has as its last electron, the 5d sublevel.

02:14 All i did was look it up.

02:16 Potassium is in the 4s sublevel...
