Nonmetals add electrons under certain conditions in order to attain a noble-gas electron configuration. How many electrons must be gained in this process by the following elements? What noble-gas electron configuration is attained in each case? (a) $\underline{H}$ (b) $\mathrm{O}$ (c) $\mathrm{C}$ (d) $\mathrm{S}$

Non metals are those which has non metals are those which are four hi, six or seven valence electrons. They had 456 or seven balancing, so in order, completely erupted. What they do is they gain electrons, the game electors, because after gaining electrons, they acquired a stable, noble gas conflagration. The quiet no gas. For example. If I talk about chlorine, we know the atomic number for clearing 72. Let's right, it's conflagration. It is going to be one is to waste to six, three years to on. We have to fight. Now it's valiant shell for this seven. That means it needs one more So what it will do. It will gain one electron, and after gaining it will for the electoral negative. ICTs inform the electoral negative all the nonmetal gains electrons and for their respective electro native rights. And after getting the electron or after forming electro negative I, it's often get complete because it's conflagration now becomes 3 to 56. That is the eight electrons in the outermost shit, so non Memphis always what they do, the all based gain electrons to completely erupted on in order to require the stable over gas conflagration on when they quite a stable over gas consolation, they attain stability becomes Steve

So let's talk about the electron configuration of non metals in comparison to noble gases. So first, we're gonna look at flooring here and we're gonna look at the electron configuration of flooring when it is neutral. So here we have flooring and we're gonna go left to right on the periodic table to figure out its electron configuration. Remember, we have the s orbital, the D orbital and the P orbital here. So if we go left to right and we're trying to reach flooring, we go through hydrogen and helium here. So that satisfies the one F two orbital. Then we go through lithium and beryllium here which satisfies the two s two or middle. And finally we go through the to P orbital here, stopping at flooring, which is the fifth spot. So we've satisfied up through two p six. But typically flooring when reacting, wants to Philip it's octet by gaining another electron, giving it a minus one charge. Remember when you gained an electron, you gain negative charge, and I just realized I made a slight mistake. This is supposed to be a five, because we only went through the fifth spot here in the p orbital. So this is two p five now flooring. When it's gained an electron, it's going to gain it in the outermost orbital, which is the P orbital. So it is going to gain one here. So it's new Electron configuration is going to be one us to to us to to he six. And this is for flooring. Negative one, not something interesting happens when it does that. We see that it's going to basically gain one electron, and now it's new configuration is going to be equal to that of neon. We've gone one electron forward here, one spot, and this is the two p six spot here win. So Neon has the exact same electron configuration here as flooring with a minus one charge. So let's see if this is still the case with a different nonmetal. We're gonna go down to sulfur. So sulfur here, we're gonna go figure out its electron configuration from left to right. Remember, we can think of helium as being over here, so we go through the 1st 2 That's one s two. We go through the second grouping. That's two s two. We go through the entire two p orbital. That's two p six thoughts. Write some of this down sulfur So far has this electron configuration. We go through the three s two orbital and then we go to the three p orbital going and we stop at sulphur, which is the fourth spot. So we have our three us too. And then we have three p four. This is the electron configuration for a neutral atoms for sulfur but sulphur when it wants a doctor and when it reacts, typically gains two electrons, so it is going to have a to minus charge. So if we're gonna write this new electron configuration, we have to add two electrons to the three p orbital, giving it its new electron configuration. Everything remains the same except for the three p orbital which becomes three p six. Now if we go look and see if this trend followed were adding two electrons. We're moving over to the three p six spot, which is noble gas are gone. So sulphur with a to minus charge has the same configuration as are gone here. So we know if we have some nonmetal, that is not a noble gaffe here and they react and they gain electrons. They are going to have the same electron configuration as the next closest noble gas

Were given five different ah metals and we're supposed to do is we're trying to find the charge for each of them. The charge is going to tell us how many elections each nonmetal gains when they react with the metal. And the recent metal and nonmetal react is to form a calm bunch. And when they do, this is to become stable and it becomes stable when they have eight elections. For the most part around that it's called the doctor room. So the metal gives us elections the nonmetal, and this becomes positive. And this becomes negative positive means that have lost elections and the negative means that have gained electrons. Right, because elections are negative. So if we look at the war diagram for oxygen, this is our first nonmetal we have to orbital's and the oxygen has a total off. Eight elections the house to in the 1st 1 and it has six amounts. I want 23 or 56 that is called the Valin Show or the outer show. Right. We called the village show the idea of doing this transfer elections. So this outer show house eat elections right either by gaining elections or losing a show completely nonmetal, since I already have so many and they're so close to eight is easier for them to gate. So notice that oxygen has sex and always to show. This is by the lewis dot structures, a 123456 So in order to go to H, which is the Octu rule, how maney electrons they need to gain any suit game to tow one two. So the charge is gonna be negative, too, because it gain two electrons, right? So we write it. I think this and charge combines air usually put in brackets. All right, then we look next. A flooring, flooring half seven villains Elections. If you're having issued than a fine balance elections, look at the column. Ignore the transition metal and this is a column. Seven. Ignoring transition metals have seven billion selections. Thereby column. The group has the same number of atoms elections it needs to gain one valence electron. So when it gains said it becomes this and said, negative is gaining so negative one. So again, one election. Then we look at nitrogen. Nitrogen has $5 elections. How many elections need to gain needs to gain 3123 So then it would look like this notice. They will have a at the end, as idea negative means again. Three. So the charges and I get a three and a gain. Three elections. The next one escorting chlorine is in the seventh column. You know, in the transition metals. So 1234567 Any suit gain one electron so that it will look like this 1234 R six oven age again the I. D s for them to have eight elections were on the in game one and again there. Negative, because elections are negative. So they gain one electron and then we have sulphur, which has six elections, six Valin selections. So does needs to gain too. 12 And then it will look like this and they shouldn't be thoughts. So negative too because of gain two electrons. So is this negative? Too many gain two elections when it reacts with a metal

This question I've been asked to determine the number of electrons that they've given elements or atoms must attain in order to have a stable configuration or a notebook a structure. So looking at the first one, we've been given calcium which has a total of 20 Electrons. That is, it is in group two with 2 autumn. A special election. So for it to attain stability or a notebook a structure it has to gain in total or rather it has to lose two election. So looking at the nearest no black cats, which is a con A total of 18 electrons, it has to lose two electrons for it to attain and alpacas configuration that looks like that off. And then moving on to the 2nd 1 where we have Libya With a total of three elected. If we look at the nearest no because configuration two lithium. It is William and helium has a total of to elect So Libby um needs to lose one electron for eight chain and no bocas structure that looks like that off syria. And then moving on to the next one where we have been given sodium which has a total of 11. And look looking at the nearest no focus is neon. But here's a total of 10 electric. So sodium needs to lose a single electron for it to attain a noble gas structure that looks like that off Neo. And then moving on to the next one where we have M. G. Was total number of electrons is no The nearest no bogus is neon with a total of 10 electric. So mg magnesium, it needs to lose two elections for it to attain a stable or no broadcast configuration that looks like that of neon.
