Is silver still valuable if its some what oxidized?
Silver has two valuesOne is it's melt value and condition is irrelevant, monetary value is simply determined by silver content (purity) and weightThis is the lowest valueThe second value is determined by what it isIf its a piece of antique hallmarked English silver, it's silver weight has only a small bearing on its valueIt's value is in being old and rare and it's condition ie not broken or dentedOxidization is common, it is easily removed, it has no bearing on value in either valuationThe easiest way to remove it is get a large plastic dish (not metal) buy washing soda and aluminum foilPut the aluminum foil on the bottom of the plastic container, add very hot water and a few tablespoons of the washing sodaImmerse the silver item into the plastic containerIt must be in contact with the aluminum foil and be under waterUse rubber gloves as the water is hot rememberDon't use metal tongs, nothing metal except the foil and your silverBy chemical reaction the tarnish will leave the silver item and transfer to the aluminum foilI'm not sure of the actual chemistry but it works, trust meIt takes a few minutes to happenTurn the silver piece around as necessaryThen remove and rinse with cooler water and dry with a oft clothIt doesn't damage the silver.
Rutherford's mentor became J J Thompson who had advanced his so talked about as plumb pudding variety of the atomHe considered the atom as electrons (plumbs) floating in a sea of effective cost (the pudding)A more beneficial modern description may be the chocolate chip cookie varietyreally Rutherford's artwork confirmed that the atom quite consisted of empty area with the effective cost targeted interior the nucleus.
