2.1 The Atomic Theory
What are the four hypotheses of Dalton’s Atomic Theory?

2.1 The Atomic Theory
Law of Multiple Proportions:
If two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element are in ratios of small whole numbers.
![Page 5: Atoms, Molecules, and Ions · 2017-12-22 · Atoms, Molecules, and Ions. Chapter 2 yThe Atomic Theory ( 2.1) yThe Structure of the Atom (2.2) yAtomic Number, Mass Number, and Isotopes](https://reader033.vdocuments.net/reader033/viewer/2022060208/5f0406a87e708231d40bf35f/html5/thumbnails/5.jpg)
Example:
Nitrogen and oxygen combine to form 2 different compounds
Compound 1:10.00 g of oxygen combine to form 18.75 g of the compound
Compound 2:10.00 g of oxygen combine to form 14.38 g of the compound
What is the mass ratio of nitrogen between compound 1 and compound 2?

Discovery of the Electron (J.J.Thomson, 1898-1903)Thomson experimented using cathode-ray tubes: ◦ high voltage was applied to the tube◦ ray was emitted by the negatively charged electrode
The ray was repelled by the negative pole of an applied electric field and also deflected by a magnetic field.
The beam consists of negatively charged particles, electrons.

Discovery of the Electron (Millikan, 1908)Measured charge of the electron:
by observing the rate of the fall of charged and uncharged oil droplets
Used the determined charge to calculate the mass of the electron

Discovery of the Nucleus (E. Rutherford, 1910)Rutherford used a very thin gold foil and alpha particlesThe alpha particles went through the gold foil largely undeflected.A small number were slightly deflected and some of those were deflected back at the source.
Positive charge of the atom is concentrated in the nucleus – protons have an opposite charge of electrons and a mass of approximately 1800x an electron
