Dalton's Theory All matter is composed of small invisible particles called atoms All atoms of a given element are alike in mass and other properties The atoms of one element are different from atoms of all other elements Law of Conservation of Mass Matter is neither created nor destroyed Atoms of one element cannot be changed into atoms of another element by chemical reactions law of definite proportions a compound is always composed of the same elements in the same proportion...

ionic compounds -deals with charged particles -oppositely charged particles are attracted to each other -look for presence of metals and polyatomic ions molecular compounds -share electrons -nonmetals -no polyatomic ions unless its an acid 00:26 01:22 Type I metals -ionic compounds -group 1A,2A,3A -one type of charge state -Name of metal +ion -if metal+nonmetal: name of metal+base name of nonmetal +ide -if metal+polyatomic ion: name of metal+name of polyatomic i...
