and this problem, we have to determine how ions of metals or metal ions would impact the activity Siri&#x27;s and the order of them specifically. And in this problem, we&#x27;re dealing with cobalt and iron. And what we can determine based on the conditions and the problem that we&#x27;re given is that cobalt is going to be below iron in the activity Siri&#x27;s. And why is this? This is because iron is oxidized by the cobalt ions. So this makes iron a more reactive metal, which is why we would see cobalt below it. So I hope that this problem helped you understand a little bit more about not only the activity Siris in its order, but how we can predict where metal ions would fall into these activity orders.

Okay, So in this question, we have to write down the formula off to Koval Oxides. Um, just remember that Kobylt is a transition. Metal under 40 can take more than one charge in this case, call to bankable three. Okay, so the cobalt irons are cool, too. On Kobol three. Any oxide will contain Occean with a charge off. Negative too. That&#x27;s the oxide. Aryan. This is the oxide. Are you okay? Okay. So the compound between cobalt positive too. On the oxide iron? Yes. One couple, one oxygen. Why? Because the code is providing to possible charges on the oxide. Are you miss? Provided providing tuna. Got the charges, then? That charge is zero. In the case off cobalt three oxide. The formula is go on to oxygen. Three. Why? Because to cobalt three would provide six charges on three bauxite irons. Will provide six negative charges under four. The neck charge is zero

Okay, so we&#x27;re asked How can an Adam they&#x27;re How can an Iron Adam form Bull Flynn Iron two plus Iron and Iron Dream, plus I, on case own plus and an iron three plus Okay, because that&#x27;s our end Election configuration is iron is f e. Uh, it&#x27;s right here has an electron configuration of close, but we asked a r and then 12345678 billion chance that for us to three d In order to form a close eye on the iron, Adam loses the outermost shell, which means that loses this for too. Which means that it&#x27;s just a r three d six and recall that r dd greedy or the orbiter could Still, at most, Gaeta left around the weight one, too. 34 I think. Go still at least 10. Okay, but that&#x27;s not the point. We&#x27;re talking about our two. Plus, we want to lose two electron because I was too plus charge. So it&#x27;s gonna lose. Its Adam will show. I&#x27;ve become a orange pds for our entry plus call again, iron is for us to three D. So we&#x27;re gonna lose two electrons from our four X orbital and then one from our three d sick. So we&#x27;re left with a three. D five when forming. The report on the iron Adam loses the forest to electrons and one greedy electron. Since it is also it will also gain stability with the house with a house build de orbital.

in the given compound. The cobalt oxidation state is for the give toe. So the electronic configuration for cobalt will be cobalt. To positive will be three d seven Onda full s zero. The chlorine atom is vehicle again During the complex formation the D orbital off cobalt split This result in tow two orbiters being in the lower energy level and three orbiters being in the higher energy. The spitting can be shown as one to three for a fight. Spin states Chlorine is the weak energy like and so it is not effective to pay the electrons with the higher energy level in complex formation. So four electrons out off seven in the D orbital goto the lower energy level orbital and get paired. The remaining three electrons in the higher energy level are unbuilt. Therefore, the compound CEO see here for too negative is better magnetic in nature

Okay. So cold up, which is a transition. Metal has both the form till 2000. Field reports for Ireland, the rest to write the correct formula for both of the oxides form by any different. Okay, so we have sealed two plus and equal to what we know that oxygen has a two minus oxidation number. So we could buy and cold by Kobe, cobalt and oxygen, which has both you plus charges are formula would be the all Oh, because our two plus and our two minor cancels to give him that charge of girl. And that&#x27;s when we got be called Kuba two outside and then more cobalt with a report charge. Uh, we would need to cobalt for every three oxygen&#x27;s and its name would be cobalt three oxide. Recall that we have to put these, um, number after our cobalt symbol because it has different oxidation numbers.

So in this podcast here, we&#x27;re just looking at when an element forms and on my own or cat ion what happens to its radiance. So on an ion has a negative charge. Catalan has a positive charge. Then we will discuss why and then following this We can&#x27;t look at the definition for the term I saw electronics and how we order atomic radio when we have ice of electronic ions, so on I owns fastly are larger and radius on neutral Atoms on Catalans are smaller than neutral atoms. So when we look at Annan&#x27;s the added electrons increased the electron electron propulsion that is experienced. In order to counteract this, the size of the electron cloud increases placing the electrons father apart on. Therefore, we have a greater radius when looking at our Catalans. As electrons are removed, there are fewer electron electron propulsion is experienced and therefore the electron cow cloud commit pulled closer to the nucleus on. So we have a smaller radius now moving on to the second part where we&#x27;re looking at, I saw electronic species so is defined as two atoms having the same number of electrons. So there are two variables here, the number of protons on the number of electrons will determine the size of our iron. So when we keep the number off the electrons constant, we have to consider only the number of protons in order to predict our trends in terms of size, so the iron will with the most protons will attract the same number of electrons most strongly due to the greater positive charge in the center, which results in a smaller atomic size.
