So we have been discussing the beginnings of the atom, and now I want to know what you think.
-who were the main characters in the development of the atom
- Why were they vital to the development of the atom
_ what made them differnt if anything
- Think about your lessons in history and discuss how the time period that they lived in determined the outcome of their discovery/ or how it influenced those individuals to be the names that we know today (aka did it matter where they grew up or if they had money?)
- Why do we consider the atomic theory still a theory? What are the new developments- would love for you to share new sources here about what you find
- Why does it matter that we understand the structure of the atom
Hey ya'll you have to post your thoughts, then you have to respond to a post from one of your classmates!
Due Date? Week of 9/20-9/24 depending on the day Chemistry sets- that includes your post and and a response to a classmate
The main charachters were John Dalton, Dmitri Mendeleev, J.J. Thompson, Rutherford, and Niels Bohr.
ReplyDeleteJohn Dalton proposed 5 theories:
Elements are composed of tiny particles called atoms.
All atoms of a given element are identical.
The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights.
Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms.
Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
Dmitri Mendeleev is credited with inventing the periodic table.
J.J. Thompson descovered the electron and developed the plum-pudding model of the atom.
Rutherford is famous for his gold foil expiriment. (which we went over in class today so whoever is reading this shoulnt need any me to describe it!)
Niels Bohr stated that the electrons moved around the nucleus in successivelylarge orbits. He also presented the Bohr atomic model which stated that atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states.
John Dalton made his theory in 1803, Dmitri Mendeleev 1869, J.J. Thompson 1898, Rutherford 1911, and finally Niels Bohr in 1913. The time periods in which the discoveries were made said a lot on the depth in which each scientist was able to go. The earlier the time period, the less resorces at hand.
John Dalton's atomic theory is still only but a theory because not all of his accusations can not be scientifically tested and proven.
It matters that we understand the structure of the atom because (knowing Roessboss) your probaly going to give us a really hard test over it! Also, everything on earth is made up of atoms and there is still much unknown about the atom and the more knowledge we gain about it, the more are generation can contribute in the future.
Cory your post sounds awesome!! You can tell you didnt make it all up!! Nice!! haha
ReplyDeletevery well done cory. this proved to be very imfomative and factual, but it seems that you did your research and then wrote it in your own words. These blogs are meant to be factual and infomative, but also to showcase your personal opinion with feeling. Throw some spice in there.
