- 1law of multiple proportionsif 2 elements can combine to form more than one compound, masses of one element that combine w/ fixed mass of the other element are in ratios of small to whole numbers
- 2law of conservation of massmatter cannot be created nor destroyed. Mass must be conserved
- 3law of definite proportionsdifferent samples of the same compound always contain its constituent elements in the same proportion by mass
- 4alpha (a) rays/particlespositively charged particles, deflected by positively charged plate
- 5beta (b) rayselectrons deflected by negatively charged plate
- 6gamma (y) rays/particlesno charge, not effected by magnetic field
- 7x-rayscannot be deflected by magnet, could not contain charged particles
- 8radioactivityspontaneous emission of particles and or radiation
- 9J.J. Thomsonused a cathode ray tube + knowledge of electromagnetic theory to determine ratio of electric charge to mass of electron
- 10Daltoncreated atomic theory
- 11rutherfordpropsed pos charges are in nucleus
