Who were the main characters in the development of the atom?
John Dalton, Michael Faraday, H.G.J. Moseley, James Chadwick, J.J. Thompson, Ernest Rutherford.
Why were they vital?
John Dalton- Came up with Atomic Theory.
Michael Faraday- Cathode and anode experimentation.
H.G.J. Moseley- Showed that the periodicity was a function of the atomic number rather than of atomic mass.
James Chadwick- Proved that neutrons, and neutral particles in the nucleus, that made up half of the mass of an atom did exist.
J.J. Thompson- Finalized name of electron.
Ernest Rutherford- Studied absorption of radioactivity.
What made them different if anything?
Some scientists kept their theories as theories, and never tried to prove otherwise, and other scientists were determined to experiment and prove their theories, etc. And they solidified their results, and the time that they lived in had a difference in how accurately they made discoveries.
Think about your lessons in history and discuss how the time period they lived in determined the outcome of their discovery?
Back then, they did not have the technology we have today. If they had the technology we have now, it could've completely expanded scientists discoveries. They could have had better equipment to work with, which definitely might have played a major role in new discoveries. They also would've been able to make discoveries way quicker, because back then, they would have to guess and test basically until they got it right, when now we could just test it with technology.
Why do we consider Atomic Theory still a theory?
We still consider the Atomic Theory a theory because there are still many things about it that have yet to be completely proven; also, it has not reached it's full potential; we still have much to discover about it yet.
Why does it matter that we understand the structure of the atom?
Because we have use this stuff in our daily life, and the basic idea of the atom is structure. It's important we know the structure familiarly so we can use it to our advantage.
RoessBoss! Mine was late because you sent it to the wrong email, remember? Therefore, cut me a little slack. I had to redue it completely. >:0
