question Number 62 is in recommendation to the specify name of ionic compounds the contain a shift metal because shift metals can have variable positive charges when creating ionic compounds. The very first thing the we need to do as soon as naming this compounds is identify what the charge on the anti top top is that typically has a constant charge. After ~ we've identified the fee on the anti on. Then we recognize the charge on the cat ion such that the Ionic link is neutral with a complete neutral charge. So, because that example, if we have hte G s, we look at the regular table we see that s sulfur is in group six, a group six A. Synchronizes to facets non steels that commonly want to take on two added electrons and also have a come minus charge. Therefore, Mercury H G requirements to have actually a 2 plus charge. Therefore we have actually a neutral compound. We would certainly then surname this mercury come sulfide. The following one is C. U C 03 Cocoa three is not uncovered on the routine table, but it is a poly atomic ion, which is really common that you should have actually memorized v a to minus charge since it has a to minus charge 보다 the copper demands to have actually a 2 plus charge. Therefore we have a neutral ionic compound. This would certainly then be copper come carbonate. The following one is N i C L 2 c. Together is in team seven A. It commonly wants to take it on one additional electron to end up being like its nearest noble gas. So each halogen in team seven A commonly has a one minus charge in one ionic compound. There are two the them, therefore that's a full of a to minus. So the nickel climate must have a 2 plus charge. This would certainly be nickel come chloride. Then we have actually C U N 03 three Uh oh, No. 3 is a poly atom ion the you should have actually memorized v a one minus charge. There are three that them, so that's a total of three minus. So the cobalt needs to have a 3 plus charge. This would be cobalt 3 nitrate, then for E. We have actually 20 h groups and also O H group. Girlfriend should have actually memorized together a poly atom ion v a one minus charge. This is hydroxide due to the fact that we have actually two of them. That's a total of two minus. So every copper needs to have actually a two plus charge. This would be copper also hydroxide. And for the last one, we have iron through eso four. Eso four is a poly atom ion the you should have actually memorized that has actually a come minus charge. We just have one s 04 So each iron requirements to have a two plus charge. To get a neutral compound, this would be named iron come sulfate.
