8ChadwickNovel experiment to discover missing mass in the atom (nucleus)Why difficult to observe?
9Periodic Table Who ? How is it organized? Know the group and series names, metals,nonmetals, metalloids,solids, liquids, gases
10Chpt 2 - Nomenclature Names <-> Chemical formulas Binary and Polyatomic Ionicper -ate, -ate, -ite, hypo -iteRoman numerals( ) if necessary in the formulaMolecules (prefixes)AcidsWithout oxygenWith oxygen
11Nomenclature Metal 1st -> ionic compound Binary - Metal retains its name nonmetal ends -ideKnow the normal charges to combine -make neutralUse roman numerals for charge on transition elementsPolyatomic ions memorize from Table 2.5Use ( ) for polyatomics, if more than 1 neededNonmetal 1st -> moleculeUse prefixes!! Mono not used on 1st element1st element retains its name, other ends -ide
12Nomenclature H 1st = Acids No oxygen, also ends -ide hydro ____ ic acidHas oxygen, polyatomic ion (Table 2.5)-ate becomes ____ic acid-ite becomes ____ous acidH+1 used to balance polyatomic (-) charge
