Current stuff: naming compounds is easy stuff so far, doesn't deserve coverage. What does is the "memorization" of radicals. I suggest first considering the oxygen-bearing ions in this task. They all have the exact same rule! Name=(di or hydrogen at the beginning if it contains hydrogen)+(name of element minus last syllable)+(suffix: ite < ate) If you use this, you will not need to memorize any of those ions, because you will be able to deduce the name, and(excluding some exceptions) the charge on these ions is always negative one.
Remember; all sulfur ions have charge of negative two, chlorine ions can contain 1,2,3, or 4 oxygen atoms, which become represented in the name as a prefix hypo- if containing one oxygen(suffix -ite remains) or utilizing the per- prefix seen in oxygen rich ions such as permagnate and peroxide. Also, easy ions to commit to memory are ammonium, NH4, one of the few stable polyatiomic cations, CN, cyanide, which is damn close to being phonetic, and of course OH, hydroxide, commonly seen in EVERY basic(ph > 7)substance. If you use all the things i have went over in this entry, you will ONLY HAVE FOUR MORE Polyatomic ions to remember!!!(maybe six if you count some of the crazy ones that she doesn;t really care about, but are fair game for the AP test)
Before i leave, it's also important that we all can do the problems from the previous chapter and no one is left behind. So, make sure you understand how to do this sample problem (pretty much as hard as basic DA gets, you don't actually have to do it if you know you get it) and if anyone can;t do it, it will be explained so we're all on the same level:
The aluminum in a package containing 75 ft2 of kitchen foil weighs approximately 12 oz. Aluminum has a density of 2.70 g/cm3. What is the approximate thickness of the aluminum foil in millimeters? (1 oz = 28.4 g.)
Keep thinking, guys. The key to this is to not take the notes blindly and ignorantly, but interpret them.
