List four ions that have the same number of electrons as neon, Ne.

Okay, everyone, today we're gonna take a look at Neon, and we want to find four ions that have the same number of electrons as neon. So let's just look at me on really quickly. We'll see that neon we draw it out real quick. His neon is gonna have a zero charge for an Adam of neon. So when we haven't Adam, that simply means that the protons and electrons gonna be the same. So we looked at this really quickly. We see the neon as atomic number of 10 so it's gonna 10 protons will also have 10 electrons. So together, if you and those together you'll cancel in both down you get a zero charge. So we want to. Dio is we want to find ions with charges that would have the same number of electrons as neon neon Adam would be which be 10. So we use the word I on. That's gonna mean that you have a charge or miss balance of electrons and protons. So if we choose something like the oxide, I would say, Oh, with a to minus, we'll see how we develop this. Well, oxygen is gonna have an atomic number of eat, so that would be eight protons. So I have eight protons for a positive eight and eight electrons. That would be neutral. Okay, so what we're gonna do is that we add two electrons that becomes 10 electrons that would now have a minus two charge. And you'll see that matches the charge on the ion of oxygen to the oxide island. If we go over to sodium, let's try that one. If you want a sodium, we'll see the atomic number of sodium is gonna be 11. You'd have 11 proton in this case, right? So if you looked at the same number of electrons me on, you would have 10 electrons again. And let's see if we can come up with our our charge. What, without charge B, in this case, well, we'll be looking at really quickly. You could see that you have 11 protons for a positive 11 and the same matching 10 electrons. So that would be a plus once. Exactly. That would be the charge. You place the upper right hand corner. All right. We could move around me on the periodic table and find some other elements that will be close by. How about magnesium? So it's magnesium atomic numbers. 12. We could say, OK, that would be 12 protons. If you have 12 protons, the most common ay on off magnesium is typically plus two. So how many electrons would you need? Here and again? That would be 10. Right? So that you end up with a plus two, which would match again. You want to match that charge? You can see how these ions with the charges. Okay, um, I'll choose one more. Maybe the nitride I on with a minus three year again, Nitrogen is gonna have atomic number of seven. So let's seven protons here, okay? And if you had this minus three now you can see from the oxygen example that would be tomb or electrons on again. That would be again, 10. You want to keep that 10 the same. Okay. And that would be our 10 electrons, which would give us a minus three to confirm. So that's how you would figure out. So really, you can see me on with 10 electrons, really matches the other ions here. Okay. And is a special name for this. His name is called So Elektronik. So I saw electronics is, um, ions or elements or are Adams? Could be. I had the same number of electrons. The prefix isil means same Elektronik, of course. Me. Meaning electrons. Okay, so just a brief recap, okay? And Adam is neutral. Okay, so this is a sodium. I'm sorry. I mag me on Adam. Sorry. And me on Adam. Okay. And you should be four ions. That would have the same number of electrons. Has that me on a Okay. All right. Thank you very much.

Neon has 10 electrons, so to be isil Elektronik with neon, meaning having the same number of electrons. Oxygen needs to take on two more electrons to become O to minus. Florid needs to take on one to become F to minus sodium needs to lose one to become any plus, and magnesium needs to lose two to become magnesium two plus.

All right there. So the question at hand is of these elements that I've highlighted on a periodic table, sodium, calcium, cadmium, aluminum and tin, nitrogen, fluorine, sulfur and burning, Which ones will form positive or cat irons, which ones will form negative or an irons. So it comes down to, first of all knowing the difference between metals and non metals. Uh so we see that we have this staircase line going along the left side of boron, Down, under, down, under, down under all the way down. For our sake, eh that line separates medals for non metals. Yes, metal lloyds are there too. But for this discussion, we're not going to worry about metal Lloyd's. So everything to the right of the staircase are your non metals? Everything to the left would all be your medals. Now, once we know the difference between metals and non metals, we should know that metals have very low ionization energies, which means it's very easy to take an electron from a medal. And if it's easy to take an electron from metal since electrons are negatively charged, it's going to leave the item more positively charged until we see that metals form cat irons. So sodium, calcium, cadmium, tin and aluminum would all form cat irons. By contrast on the other side of line we have the non metals. So we're now getting closer towards the noble gases towards that octet, we have elements that are high in ionization energy which means it's hard to take an electron from them. But they have high electron affinities and high electric negativity is which means that it is very easy for them to pull on extra electrons, making them negatively charged or helping them to form an alliance. So nitrogen would form a nitrite iron flooring with former fluoride iron. So for a sulfide iron bro, mean a bromide iron all negatively charged. So there you go. That's what it comes down to. Mm

Alright, we're gonna do some chemistry today. So what I want you to do is take a minute pause the video, read the question and try to figure out what exactly they're asking for. So now that you've done that, let's get into what they're asking for. So to summarize they're looking for, they're asking about these elements and which of these elements would be found as negative ions and which of these would be found as positive ions if they were found in binary only compounds. To begin answering this question, you need a periodic table, Like the one I have right here. All right. Now that you have a periodic table, what I would begin doing is then underlining all the atoms or elements in question, which is all these. So, I've already taken the liberty of doing that and they're all underlined in red. Right? So why we did this? Right. So we did this because depending on where an element is in the period active. Well, you could uh predict how likely it is to be a positive or a negative ion if they were founded by narrow on a cop. Right. So a good rule of thumb is that metals are typically positively charged in a binary ionic compound and non metals are typically negatively charged in the binary ionic compound. Okay, so in this case all the medals are in yellow boxes and all the non metals are in green boxes. Okay, so the next thing we need to do is create a list of positive violence and negative violence. The positive islands list would contain all the underlined um, elements in red that are found in yellow boxes. And all the negative violence list would contain all the underlying elements chad and green boxes. So take a minute and pause the video and try to do that yourself, hurry Not. I would like to add that. These are the typical charges you can find on some of the elements in question and also the ones that are not in question. But I've also had the answer right here, which I will bring to the top to make sure we've got right. So we made our list already to make sure calcium C. A N. A. So this would be positive cd. This cadre. Um I sent 10 an ale aluminum, all in yellow marks, negative ions. We have romaine, nitrogen, which is N. Flooring, which is a has just help her All together. 1 234 5678 nine elements in question. 1234567899 Elements contained in our hands. So they should be correct until next time.
