Atomic Structure

- Don't worry my 4 theory's are here to help.
- This H2O might be positive.
- When I say something dense and hard, I do not mean this car.
- Dalton's 4 theory's are elements made up of small inseparable particles called atoms. His second theory is same atom same element, different atom different element. His third is two different elements make a compound. Finally his last theory is in a chemical reaction the atoms are moved, but they are not changed.
- There is too much energy in this class.
- In 1897 Thompson discovered electrons by experimenting with cathode ray and a tube. He found out cathode rays are negatively charged, while he found positively charged particles in neon gas.
- Mines Better!!!
- No!! Mine is
- Once apon a time in 1909 Rushford did a gold foil experiment. He chose gold because it was the most malleable metal. He concluded that in order for the alpha particles to come back they had to had to hit something hard and dense.
- THE END!!
- The bohr model represents electrons and energy around the nucleus. It shows the electrons in atoms are in different orbits around the nucleus. These orbits can also be called energy levels. He came up with this in 1913.
- The main difference between these two crazy people is that the Bohr model has the electrons in fixed paths, while the other one has them going everywhere.
- goodbye
