Dalton's Atomic Theory correct answer: 1. Each element is composed of atoms 2. all atoms of a given element are identical all same in each individual element but no two elements are the same 3. Atoms can not be recreated by a reaction. Atoms can not be created or destroyed (law of conservation of mass) 4. A given compound always has the same relative number of atoms (law of constant proportions) JJ Thompson correct answer: did a series of plum pudding experiments with cathode ray tubes ...
