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.

Now we'LL discuss the solution for a problem seventy six from chapter six. In this problem, we're asked to write to condense electron configuration for the following Adams and indicate how many unpaid electrons each has. So let's go ahead and start for part A. We were given a magnesium so the noble gas configuration for magnesium would be neon And then the valence electrons we have only two. So it's a three s to orbital. And because both of these electrons are paired in the S orbital, there's zero impaired electrons for part B. How were given Germaine iam she and so the noble gas would be are gone And then we have a forest too. Three. D ten and forty two. And since we have two electrons in the pure battle, they'LL both be impaired. So it's too paired. Electrons for part c were given, bro mean so this will be again are gone followed by for us too three B ten and for p five. And since we have five p electrons to will have two pairs and then we'll have one unp aired in part d. The elements were given is the nadiya, so they have are gone, as are noble guess Electron configuration And then we have three D three for us two. We could also write for us to three d three. So since we have three electrons in the d orbital so I'LL be unfair dde for part ee we're given atrium. Why? So no gas configuration for atrium is krypton And then we have forty one five us too. And here we have one unimpaired, which is the orbital. And then finally in the last part part f we have loutish Um Oh, you no gas configuration is zine on. And here we have f Orbital's involved. So we have four f fourteen five the one six s too. And here the d orbital is thie unp aired electron are possesses the unpaid electron and all the others are paired.

That's right. The condensed electron configuration for each of the following elements. Gallium gallium has 31 electrons and electron configuration is are gone for us to three D 10. Mhm four P one. And it has one unpaid electron for b calcium, Calcium has 20 electrons. Cores are gone for us to has zero um paired electrons for C you know, vanadium Just 23 electrons. Her guns for us to three d 3. Canadian has three and electrons for D 18. Hi Dean has electron configuration. 53 electrons. Krypton B five, S 2 for the 10 Mhm five P five. And I then would have one unpeeled electron easy Gayatri. Um 39 electrons. This would be krypton Mhm 52. Yeah. For the one having one NPR electron. Okay. For f platinum. Platinum has 78 electrons. Corum Xenon six S two five D eight. Yeah. And platinum would have two. Yeah. And paired electrons. And Fergie. We have Lucci. Um and lose him. Who will have 71 electrons. The configuration here? The Xenon Yeah. Six S two five F court. I mean four F 14 Story. Mhm. This would give us or 70 for F 14 five D one. It would have won. Mhm. Uncared electron

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.

The question given us from the topic electronic confirmation and period. This question is as that right. The electronic confirmation for the valence electrons of elements in the first three years in group A. To eating. So basically this question is asked that what is the economic contribution that the elements of Group one group which is one a two a day. As in the first three period. Basically the elements that we have in the in one A group. Mhm. Is hydrogen, you too sodium. So the configurations of these elements would be i this would be one is one for the return would be one S. One. But with them it would be the noble gas which is helium the worst one. And for sodium it would be the noble gas, neon three is one. So that is how we can write the contribution of one age group now. Or do we? Okay. The elements that we have in first we don't have an element for a second period. We have very long for the second period. We have barely. Yeah brilliant and magnesium Berlin has and this is the number of one. This is the number of three and that's the number of 11. This is this is the number of four and this is the number of 12. So the contribution would be helium which is one is to who is to this would be neon which is 10 plus two. That would be too is to moving on to three configuration from three. It is us that there are three in this context also will have two elements boron and aluminum. More on five aluminum 30. The confession of autonomous shell would be helium. Okay the risk helium two S two 21 here it would be neon three years two should be traced to. She is too Tp one for for a. Well the first the three periods so fast. There doesn't have an element. Second bird has carbon and silicon in it. So the contribution will be one more than four on and one more than 11. This will be six and this would be 14. The conversation will be healing us too. I'm an helium to waste too. And two people it would be neon to history gp. Moving on the next one. Uh huh. In five the elementary have our in five. The elements we have and the flash but we don't have in the second grade we have nitrogen just five and first photos which is 15 and nitrogen which is seven phosphorus which is 15. Yeah the continuation of this would be optimists. It would be neon and so helium. Yeah. Yeah the west to will be 33 plus two and this is 21 is 2 to 3 phosphorus would be so this should be healing. It should be helium. Hey liam was too and they should be neon. The normal has been provisions two years to three P three. Moving on to six A one 61. We have in the the second period we have fleury oxygen eight and sell for 16 oxygen has a contribution of one more than nitrogen meaning helium which is one is to the west to and before oxygen would have a contribution of Eon three years two TP food. They cannot have the similar confirmation because they belong to the same group 78 and 80 are the last to which we provide in 78 1st but has no element second period as floating which is nine and chlorine which is 17. The conversation would be alien which is one is to two ways to 35 and hear the confession would be neon three years two 55. Now in the last one which is the eight A group. We have the one element in the spirit which is helium, one is to and neon which is the fully full conviction. 11 has to do is to 36 then we have Oregon. It has a configuration of one is two. It was too B six three years 23 physics. These are the contribution of develops restaurants. We have for these particular uh elements. This is the condition ability last night's electron blaster There the contributions that we have for the valence electrons of each of the element mentioned. This is a town valence electron violence at trump. They are all the village returns or the olympics. Yeah.
