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. It is found that the elements acquire charge either positive or negative, only in order to achieve the nearest noble gas configuration, that is found to be the most stable configuration.So let's talk about first our main group elements. And in this way we can know the charge of an element from the periodic table. We can simply say that electronegativity increases towards the right side of the periodic table and electropositivity increases towards the left side of the periodic table. Let us take an example of sodium that has electronic configuration of $1$ and is an electropositive element which is placed in the left side of the periodic table. As we know that all the electropositive elements are placed in the left side of the periodic table, and all the electronegative elements are placed in the right side of the periodic table. We can know the charge of an element from the periodic table by seeing its tendency to either attract or lose an electron. Whereas, most electronegative elements are placed on the right side of the periodic table. It is found that the most electropositive elements are placed on the left side of the periodic table. Hint: As we know that charge on the ion is either positive or negative.
