字幕表 動画を再生する 英語字幕をプリント Welcome to another tutor sure provided by the Educational Support Services Department up the high carbon Community College in snacks fell Pennsylvania which is just outside a valid tell these videos review key learnings for the science courses provided herein tell Tracy completion member that the Educational Support Services Department does provide walk into during five days a week this video review the basic naming conventions that we use for ion I can call failing compounds in chemistry house start at the bottom here just two to let you know that I E um will review how to deal with transition metals and I am compounds on the next slide in this video and that for polyatomic ions in acids I'll have a separate video that you can look up and use but if we start with basic Diana compounds how to compounds are a metal in a non-metal combined together and the naming convention is the metal is just um stated its full name and as a second term you will state the non-metal ru plus you landed with I D E and I'll show you the first example a sodium chloride you name the metal strictly sodium and the non-metal here is chlorine hand you take the route of chlorine which is Clore celo Chlo are and added and I D E risen indeed so its sodium chloride when you move on to the next example you'll see lithium sulfide you notice the metal you still just say the the full metal name lithium you do not have to address the subscript authors to hmmm and then for sulfur over here nonmetals the routers SU LF and then he had the ides a sulfide and then the last example I have aluminum oxide again you just state the metal you don't worry about the subscript and also here on the Tom non-metal you do not worry about the subscript you um you represent an oxygen here this the route is all wax and edger I D E for aluminum oxide and Dom so the subscripts um welcome into name mean hun I am account pounds that's basically because you can look at the to charges %uh home-based charges of aluminum in oxygen you out you know aluminum oxide must be al2o3 see only way it can be formed up so you don't need to show any representation of the subscripts now we go to Cole valence there you do home have to in some way address the subscripts and so Kovan its are non metals with another non-metal to prefix here in green that's how you address the so serve hmmm subscripts in the elements so like for down down here in SF's 6 you gonna deal with the 6-foot-2 in some way with a prefix prefix as to be on either term the first others second and the the next one down here you'll see a when the two in a 5-4 gonna have to deal with those prefix though such scripts so let's look at our first one nitrogen oxide we have no: because the subscripts here are both won hmmm you do not need to use a prefix model model represents one %uh but if the Nomad the basic um nomenclature for cough and a compound you don't need to use model Hudson if you don't see a term it's implied that its model so you not the same model nitrogen it's just nitrogen safety and a second term its oxygen with the the room with the iDEN date so it's oxide you don't have to say mono now you will obviously come across some exceptions are very common one that yeah I'm sure you'll deal with your science classes see all which is carbon monoxide in there they do use um the modern form on oxide but that's just %uh a long time use it's not really following the namee a convention but it's just been you so much over the years that everybody how uses it that term now so that is one exception a and there are few others occasionally you may come across with the model term so now we look at the next example we have here um solve for with 6 Florence again because sulfurous a single element there you just use the full term of sulfur but now on the farm the fluorine you going to use a prefix hexafluoride represents six your roof for fluorine is fluo our floor and then your iDEN deed salt sulphur hexafluoride in our final example here for Oracle valances and 2005 here you need to use a prefix a dying nitrogen and a gurney you sure pentoxide pentoxide so you're prefix you wrote when you're heading there suffix if I D so if we now move over to our seconds convention here I wanted to get rid of this their ego um if we have a transition metal in arianna count pound transition metals um most of them are some other can have more than one oxidation state and so you need to address that in the name me so for transition metals you you name them that'll but you also have to give some indication up with the oxidation state is you do that with the Roman numeral and then again UN with here your non-metal routine your ID sonar first example with iron um chloride I say if Iran chlorine in this case hired here is hired three witches FEC plus 23 that's the %ah oxidation state of iron in this case so you have hired three Roman numeral 3 here %uh chloride the route and the ID the suffix the Nexus sample here CEUs this case its copper to sulfide and a copper here represents its oxidation state is close to you notice in the next example see you to s--- here the oxidation state a copper is plus one it so its copper one sulfide so by doing the one in the two you can rip you know where the you have CEUs for cu2+ s so it's important when you have a transition metal with multiple oxidation states that you introduce om this Roman numeral convention and then again as I mentioned ball have another video here in polyatomic ion said in Aus on a min yes it's thank you
