Step 1

Ionization energy generally decreases as we move down a group and increases as we move across a period from left to right. So, we can arrange the elements as follows: Fluorine (F) > Sulfur (S) > Phosphorus (P) > Magnesium (Mg) > Potassium (K) This corresponds to Show more…

00:01 Okay, so we're asked to arrange.

00:04 We have three things we're going to do.

00:11 Decreasing, first ionization energy.

00:29 And we are given, let me see if, yep, we're given f, s, p, mg, and s.

00:46 Decreasing, so this will be decreasing, high to low.

01:04 Did i miss one here? fluorine, sulfur, phosphorus, magnesium.

01:13 Oh, and this one should have been k.

01:17 So k will be the lowest, mg will be the next lowest.

01:22 Fluorine will be the highest.

01:27 Let me get over to my periodic table, s and p.

01:38 So the answer you should pick for this one is, choose f is greater than s is greater than p is greater than mg, s, p, mg, k.

02:06 Okay, that's our first question.

02:11 Our second question is, according to hund's rule, unpaired electrons.

02:20 And we are given strontium, zinc, and germanium.

02:40 So strontium has two electrons, so no, that's not it.

02:53 Zinc will have a full d, so no.

03:03 Germanium, in its p sub -level, will have one, two.

03:12 So the answer is germanium.

03:20 Germanium has unpaired electrons.

03:26 Now, for my last question, paramagnetic, which means it has unshared electrons.

03:49 And we're given beryllium, which is no...
