![]() ![]() Okay, because it's more spaces that you have to jump to become a noble gas this way. Okay, so it's easier for aluminum to lose three electrons than toe. And when it comes to cameras for week chemistry, we always go in the past. Instead of trying to gain five electrons, it could just try toe lose three electrons so that it has electrons like neon. Or I could do something easier than that. You could try to gain five electrons to have 18 electrons, just like Argha. It could either try to gain seven electrons to get it. So when it's neutral, it has 13 electrons. Now aluminum here, its atomic numbers 13. ![]() They're all metals, so they all wanna lose electrons to become like a noble gas. But we can talk about the elements below boron aluminum all the way down to NH. They have characteristics of both metals and non metals, so it's a bit tricky with them, so we won't be talking about moron. Now let's look at Boron and the other elements that are within this group. So just remember when it comes to tin and lead that can be plus two or plus for their, uh, interesting situation when it comes to the periodic table in charges. They can either be plus two or plus four for their charges. They kind of have characteristics similar to transition metals. Lead and tin are here S N and P B because of where they're located, how far that down they are. Now, though, we do have an exception that that's around exception one, and this pertains to lead and tin. Or you could try to lose four electrons so that it has to like helium, So it's kind of in a special situation, So as a result of this, we kind of just say not applicable to Group four based on their location. Either way, what I mean by that is carbon could try to gain for electrons to become like neon. The elements are in the blue Boxes group for is older tricky, So group four is equal distance. So these negative charges, when referring to them, is predominantly with the nonmetal the blue species. But then we have metal Lloyds and then we run into medals medals don't wanna have a negative charge, would have a positive charge. Now, of course, uh, some of these groups that gets tricky because in group Five we see that we have non metals here, so they have a negative three charge. So this charge, the charge of this group is normally minus three. So to get to 10.5 the game three electrons. So this group six say it's charges normally negative too. So same thing with software has 16 and have to gain two electrons to become just like are gone. How many electrons would it need to gain if you said to you'd be right. Oxygen, oxygen, when neutral, has eight electrons to have 10 electrons like neon. ![]() Because, remember, gaining electrons gives us a negative charge. By gaining that one electron, they would get a charge now of minus one. So each element in this column would have to gain one electron to become like the noble gas next to it. Electron chlorine has 17 electrons with neutral to have 18 like are gone again and have to gain one electron. If it wants toe have 10 electrons like neon, it would have to gain one. Let's look a F Flooring has nine electrons when it's neutral. Let's look at groups 78 all the elements of groups. They don't need to gain or lose electrons. So noble gasses, since they're perfect, their charges. Elements try to gain or lose electrons to match each number of electrons for the noble gasses. Arden has 18, and as we go down, these are all their atomic numbers, which gives us the number of electrons they have now. They have the optimal number of electrons helium has to Neon has 10. Now we said that all these elements of the periodic table are all trying to become just like our noble gasses are Group eight a elements. And here, if we're dealing with a neutral element, it'll have the same number of electrons. So beryllium a year has an atomic number four, which means it has four protons. For a neutral element, it's number off electrons is equal to its number of protons. For example, we'd say that beryllium has an atomic number four, so it has four protons. Elements now recall that the atomic number, which uses the variables e of an atom, equals the number of protons within its nucleus. We'll talk about those later on the four. ![]() Remember your main group elements are the elements found in Group One A or Group one, two way or group to and then from three, a tow eight A or what we call groups 13 to 18. So let's talk about first our main group elements. ![]()
