Beginning of Chemistry

1. who were the main characters in the development in of atom? John Dalton, Micheal Faraday, Dimitri Mendeleev & J.L. Meyer, Ernest Rutherford, Niels Bohr, Max Planck, Albert Einstein, H.G.J. Moseley

   why were they vital to the develpment of the atom? John dalton had published the atomic theory in 1808 with his work it explained that all the atoms of an element are the same size and weight, and atoms of the elements unite chemically in simple numerical ratios to form compounds. Micheal Faraday had backed up Dalton's theory with his law of electrolysis. Dimitri Mendeleez & J.L. Meyer simultaneously created the periodic table which arragned atoms of different elements in order of increasing atomic weight so that elements with similir chemical properties fell into groups. Enerst Rutherford developed the first coherent explaination of the structure of an atom in 1911. Niels Bohr applied the quantum theory and proposed that electrons could circle a nucleus without radiating energy in orbits for which their obirtal angular momentum. Max Planck & Albert Einstein developed the quantum theory. H.G.J. Moseley showed that each nucleus was characterized by and atomic number, equal to the number of unit positive charges associated with it.

   what made them different if anything? some contributed more the studies of atoms but all still learned from others discoveries and theories.


4. 
   
   Think about your lesson 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?) the scientist in the earlier time periods to the discovery of the atom didnt have as much technology to further explore and learn and that would be a major factor also money is a great way to gain your status in the scientific word mostly because money makes the world with turn and without it they couldnt further their education and research the atom.


5. 
   
   why do we consider the atomic theory still a theory? what are the new developments- would for you to share new sources here about what you find? several scientist have tested the atomic theory and proved 2 parts of the theory to be untrue and not all atoms are the same depending on its atomic weight, isoptopes, the element and several other properties including mp & bp.


6. 
   
   why does it matter that we understand the structure of the atom? to better understand chemistry and the elements around us and their atoms we must understand what the structure of those atoms and how many protons, neutrons, and electrons, its atomic weight and many other properties to classify the elements.
