Alexander the great
Fixed Weight and Properties
Dalton
Cathode rays “that is supposed” to the ____ to ____
Cathode to anode - William Crookes
He meant in a vacuum if other cathode is to pumping. Some will glow
J.J Thomson
Discovery of Electrons
Cathode ray particles are same mass, ratio identical
Plum-pudding model
Tinanggal ung kineme kineme tas may mas ratio na? compared san ba?
Electrons are identical and Components of all types of Matter via how?
Robert Millikan - Hydrogen x Mass ratio
ig kinorelate nya ung mass ng electrons and hydrogen kaya I and C
Alpha particles at a metal film»_space; Nucleus
Ernest Rutherford
Electron Quantized
Niels Bohr - Modern atomic theory
(Basic law of Matter) Mass of reactants = Mass of the product
Law of Conservation of Mass - Lavoisier
(Basic law of Matter) Compound contain all the elements in the same proportion
Law of Constant Composition - Proust
(Basic law of Matter) Elements in a compound > Chemical compounds in small, whole-number ratio
Law of Multiple Proportions - Dalton
4 Dalton’s Atomic Theory
Law of Chemical Composition:
* Atoms has identity
* Atoms of the same elements are identical
* Simple numerical ratios > Smallest possible unit particles of a compund
* Atoms can combine to itself
