Write electron configurations for the most stable ion formed by each of the following elements. Do not use the noble gas notation. Write out the complete electron configuration.

When determining the charge that an element commonly has when forming an ionic compound, it's helpful to know the group in which the element is found because because is the group If it is a representative element meaning found in an a group using the american convention, then it's charge can be identified with its group number. So here's a periodic table showing the group numbers, both the pack system and the american system. Using a sbs and roman numerals. If the element is found in Group one A, its charge will be one plus two A two plus three A. Three plus four A four plus if it's a metal or four minus if it's a non metal, but typically a four minus is not common for these non metals. Three, sorry, five A. Would be three minus six A. To minus seven A one minus. So where's beryllium Williams in this location? Group to A. So it will form a two plus charge in an ionic compound. 10 is in this location, so it will form a four plus charge in an ionic compound, phosphorus right here in this location, so it'll form a three minus and then sulfur in this location here, forming a charge of two minus.

So we are asked which of the ions. So we're looking at calcium plus, so a single positive charge and then incl Ori chloride minus single negative charge in which of those electron configurations of which I on um, uh corresponds with that of the nearest noble gas. Um, so let's first find calcium, calcium and chlorine all right over there. But those are the neutral element stripe, and we want to find the closest noble gas. So if they're gonna Forman I on the nearest noble gas on the periodic table is going to be hard on. So we want to see which electron configuration will look like bargains configuration. So remember that electron configurations are the, I guess, like the letters and the numbers as opposed to me arrows, which are the orbital on configuration. So come to read out an example. So for chlorine, right to form the electron configurations is just neutral chlorine. We're going to work up, left to right and then top to bottom. And so, looking at the top left, right, so we're at the first period. That's the one s orbital, and chlorine has a full one s orbit. Also, it's gonna be superscript two. Um uh, ratchets. Write it as an exponent, basically on. Then we have when we get down to the second period, Um, and there is the fool s orbital and then the full P orbital S. O. S or both. Hold two electrons. So B two s superscript two and then the next moving to the right. You see, on the to p orbital, which it's full recording so it can hold six electrons of Super Script six. And I'm moving down to the bird period. Well, we're sodium. Is that well, that would be three us to school. So then we get to on the three p for little, and we see that chlorine is the fifth element in that period. In that I guess the the P block over there. And so that means it has five electrons in that three p orbital's. That would be super service, but okay, bombs, then let's right the election configuration for calcium, and basically it is it starts off the same way as chlorine. So, for council, you know, this is just the mutual element. Uh, so one of us to to us. Hey, thanks. 32 and then for three p, right? It has the full 33 orbital. So creepy bricks. So now we're off at the fourth period where counseling is that and receives the second element there. So that means it has the fool s orbital's before s Okay, so we're asked, um let's see, uh, whether the electron configuration of how soon Russ or chlorine minus will look like pratts of our guns. And so looking at, um So if we were to create the chlorine Negative. So the chloride ion uh, we're basically adding a six electron to that the repeat orbital. Great. So we're gonna change the three p. So to make the Cory violin, we add an electron to repeat. So we form three p six. I went to form the house soon. Plus right. So when it becomes positive, we're losing an electron. And so, since it's a single positive, we're subtracting an electron and the outer orbital there's the for us. So it becomes for us one. And so, Richard, these two looks like art ons. Well, organ doesn't have. It's not in the fourth period. So there's no. Four s and it has a full three p six, um, workable. And so we can conclude that chlorine, the chloride ion cl Mya's, um, has the same electron configuration that's that of our lives.

The atomic number off L. A is 57 so they are go to 57 electrons. But in l A tree positive, there are 54 electrons on the configuration will be success to five day one or option B sm. The total number of electrons is 62 violin, sm three positive. There is a loss of three Leckrone, so the total number off electron will be 59. The electronic configuration will be six s 04 F five for option C. The daughter number of electrons is 71. The electronic configuration in military positive that is loss off. Three electrons will be 604 f 14 five b zero.

Chapter three problems, sixty four says, Predict the charge of the island formed by each element and write the electron configuration of that. I am the child. The iron is based on its valence electrons. Just review how we determine avail. Intellect. Trying for your table. We're going to ignore the meadows transition metals. They focused on Lee on being group elements, so Group one as one group to us, too. Group three A or thirteen has three for air, fourteen has four five. Air fifteen has five six Air sixteen, six seven a seventeen seven and, lastly, eight eighteen Has ete having for these mangrove elements. Having eight valence electrons in the outer show without her energy level is a full octave. When it comes to reactivity, electron elements are going to shift so they're able to share or transfer their electrons that you have eight in the outer energy level, or zero in the outer engine level, an empty our ninja level than the one beneath having eight. Let's look at what we have. The first thing we have is magnesium. Let's do this in black Magnesium, based on our periodic table, is in Group two. That means it has to man's electrons. It could either lose those surveillance electrons to have eight in the lower energy level or gain six toe have eight and that energy level. It's easier to lose, too, then to gain six. So magnesium is going to lose two electrons. And because electron there negative, that charge of magnesium is going to be plus two. And that means it lose to Electra someone else. I'LL lose too. Electrons Alfred Lose now, as do Maxygen. Nitrogen on the periodic table is located in a period fifteen or five. A. Therefore, has five aliens left. Charms. Nineteen is going to do the same. It's either going to gain three to have a total of a full octave. Have a total eight and the outer energy level or it'LL lose five to become for the lower energy level tohave the maximum or maximum number left transcendent outer level. It's easier to gain three than to lose five. So imagine is going to gain three electrons and have a three minus charged as a lion G for gain three elections. Next we have florrie Florida is a halogen, therefore is located, and Group seventeen or seven eight and has seven valence electrons. It's much easier for Floren, too. Gain one electron to have a full energy level. Then it would be to lose seven. So Florence could have a minus one charge because it gains one electron and one electron is negative. Lastly, we're looking at D D. A. N A. And A sodium and sodium is located in Group one right here. In order for it to have a full outer energy level, it's easier for it to lose one. Then it would be for it to gain one, two, three, four, five, six seven. So study was going to lose one electron and have a plus. One charge moves one electron. So now that we've identified the charges magnesium plus two Mexican three minus flooring one minus, and so Odeon less one, we're going to use this information to write the electron configuration. Magnesium plus two means it has to less electrons than a neutral atom. The knish Adam of magnesium has a tunnel number twelve. Pull my visa. Murat has atomic number twelve. That means a neutral Adam has also twelve protons until electrons. The magnesium plus two has tenuous trans, so we're going to draw the electric configuration of magnesium with ten elections. That means we have one US two to us, too into he sics This outer energy level is full and total. Six, seven, eight, six, seven, eight, nine ten electrons. Now let's look at nitrogen. Imagine, we said as a free man in charge. The atomic number of N nitrogen is seven. Therefore, it has seven protons and seven electrons as neutral. But if it's three minus, that means it has three more electrons than protons. Given that electrons and negative, so night vision would have ten electrons. So we're going to write that, like transfiguration for nitrogen. One has to to us, too. Two p six, as you notice is, the exact same electron configuration is my medium because both of these are going to have the same noble gas configuration when it becomes it on gains or loses electrons. Let's now look at Florida. Florian is minus one florins. Atomic number is Listen, I and he has not protons in an electron neutral. It was a minus one charge. Gaze one electron. That means it has a total of ten bathing tin elect shots. You might see a pattern here. This electron configuration of Florian is the same of that as an ion is the same of that of nitrogen and magnesium because they're all going to lose or gain electrons to have a full energy level, which would be the same number. Electron is Nina, our last example. A Sicilian civilians plus one. Let's check out the attacking and sodium that is eleven, which means eleven returns and eleven electrons. With neutral, Howard's sodium becomes plus one, which means it loses and electronics that I'm having eleven electrons. It has to, and as you could expect, it's going to have the exact same electron configuration. When it becomes it so, meadows and non metals only become irons. They gain the noble gas figure configuration of the closest noble cats. In this case, it was me.
