Write full electron configurations and indicate the valence electrons and the core electrons for each element. (a) Sb (b)
N
(c)
B
(d) K

In this question, we're told to write the electron configuration off some elements use and, uh ah, the electron for the noble gas in brackets. The 1st 1 is, uh, loss for us. So he's for us for us. And, like we know, uh, Group five and Pio three. So the, um no gas before boss for us is that sports for us is gonna have a neon course of puts me on our kids and force for us team. So it's something Mumbai's 15. So a new on his thing, the darkness will have five electrons, the few So because force for assists in the Group five refined for have three s u orbiter and three p uh, three. So this is the electron configuration of force for us. Then the next one is Jemaine Iam Jimmy No. Is the ah attitude too, Andy. Ah, noble gas. Immediately before Jemaine Ian is gone. So, Jimmy for so we have ah foreheads Chu. It's your call because we have the three d hospital after before communion then, uh, the three d then because the the rules for the transitional, um intended would sink and congregation for think it's poised to three d 10 with hug on core. Then we can think about hot in the heads and the p ha bitter. Which case is gonna be, uh, left with four p to be hided. So that is gonna be for pizza, because the germanium Mr Second Element in the P block off the road So that's gonna fall, teacher, Then the next one is zirconium. He atomic number 14 and the local gas before he's is oh, equipped. And, uh, it will have ah, five fest arbiter. Because the strong team we have a five past two, right? And then we'll be left with three d. I will be left for D and Zach. William is the second transition elements there is gonna be for, didn't you? The next one here is how you die. How you dying? He's, uh it is the 50 times. Hello? So, atomic member of 53 the noble gas before hit. It's also Krypton. And, uh, I ordain Haas transition element in between hit before he's so that's gonna be five years, too. And a 40 hot hitter. Or if you told us well, but the Paladin send api block. So being in the P block is gonna have five years and life be Harvard. So very few to five solitary young leopard of fight be on how many electron should be in five. So we can determine that by economic group number two, which hired him for I didn't fall in group seven. So this, uh now the Group seven habitually have a s on the PR bitter. But he has hobbies having to withdraw on hand of Pluto haven't by director. So here were refuted Hess Orbital which the electron and then hunt off seven ups used to your left. And this is the electron Congaree ship off this element.

When writing the electron configuration for all of these elements were going to shorten the configuration they put in the previous noble gas and brackets. This is there for saying that it's full up through this noble gas and also these extra ripples. So let's just walk through all four of them. So starting with P. P has a black dot on it, which corresponds to this black mark here just to be clear throughout all of these. So for Pete, we go back to the previous noble gas, which is neon, and you put any in brackets and then we go over to the 1st 2 electrons here which are in the S orbital. So since this is the third s orbital down, you say we asked to, and that's full. So we move over to the pool P orbital. And if this was a noble gas, we would expect all six to be filled. But for PB of one too. Three electrons that are impaired. So it'll be. Wreck it and eat three. Yes to three B three moving into the next one. You have geranium. Once again, we're gonna go all the way back to find the most recent noble gas that's are gone. They are. So you're gonna put that in brackets, and then once again, we're going to move down and look at the Astor petals were one road down. That means we're now in the four ass orbital instead of the three s and all to both. Two of them are filled, so that's a full orbital. Next, we have to remember the D Orbital's air here, and we have all 10 of the Dior barrels filled. So we just need to write three d 10 and focus on which of the P orbital's are filled. So we would expect to have six if it was a noble cast once again. But we just have these 1st 2 filled so every four P too. So for this one, it's bracket are close. Bracket for us to is filled three d 10 always filled, and two in the 42 jumping down to see are gonna move back to the most a recent open gas, which is K r. With that in brackets. Once again, this various allergic last one we moved to Rhode Island. So now we're at the five s orbital. That's full five ass, too. And we moved to the D Orbital next, and there's two here. We also moved on a roll with one set of three D, right, 40. And there's two electrons there, sir. Just to. And finally I I is one away from a noble gas, but we still have to go all the way back to K R, which is a similar dizzy tr to care. And Breck, it's once again five. Stu is filled. This entire D orbital is full. So that's we moved down 42 and and then in relation to G. Even with that one and then you have to come into the well it turns. Behalf sets for five total one missing. It would be sexy with a full as we wait 55 for the last one. It's bracket king our bracket five us to to fill the S Orbital's 40 10 Is that sorry 40 10 to feel the d orbital and then we have five in the final piece

So we'll write the electron configurations for each of these four elements. We want to separate the core electrons from the valence electrons. Um So I'll do the core electrons in black and then the violence in red for each. So, um Mhm. This is the S block, the D block P block and then energy level 45 six. All right. Um so we have krypton is going to end in four p 6 one S 22 S two two P 63 S 23 P six. And because its energy low for the um all electrons in the fourth levels of the four S in the four pr the valence electrons. So, for S two and four P six. All right, next we have uh germanium which is right here and in for us to so the same core as script on. Yeah. Yeah. Okay. Mhm. And then again, because we are an energy level for those are the valence electrons. All right, next we have chlorine. So it's going to end in three p 5 that people take it. And anything in the 3rd energy level is a valence electron. Okay. Finally, Strontium, which ends in five S 2. Mhm. So it's basically like continuing from Krypton on With two more elections tomorrow. Okay. Okay. Welcome to the show. Yeah, let's get okay. Yeah. Mhm. And because we're in the fifth energy level, the five S electrons are the valence electrons. Everything else is the core electron.

So electron configurations. This is the distribution of electrons of an atom or molecule in atomic or molecular configurations. Orbital's So the electron configurations are renounced, probably our farm principle on demand along filling rules. So our valence electrons are associated with an atom that are able to participate in the formation of a chemical bond. Firstly, we have KR with our configuration. There are no one pad electrons. However, we have eight valence electrons in the forest to the four p six. Next, we have G e. With our electron configuration, we have four valence electrons that are in the forest to the four p. Two. So we have to and paddle like drunk. Here. Next we have chlorine. This fills neon three s 23 p five. So we have seven Vaillant electrons. That leaves is with one Vaillant with one on pad electron. Where are seven valence electrons in the three s 25 p. Five. Next we have s r, which feels chaos in the five us to we have to Vaillant electrons in the five s two with no one paired electrons. So just one Looking at orbital diagrams, we draw out our two electrons per orbital that are opposite spins for So, for example are s shell can hold two electrons, which is one pair. This isn't a shell. You can see that we can have one up spin, one down spin and then just one more example We can have or peel beetles so we can fill with six electrons which equates to three pass.
