Hisotry of Atomic Thoery
Democritus developed the concept of the atom in 5th Century B.C.E. However great thinkers pushed this theory down and was not brought back until the 16th and 17th century -
Christiaan Huygens
Christian Huygens founded the wave thoery of light aswell with major developemnts in mathematics. -
Issac Newton and the Return of Atomic Thoery
Newton studied gases and the possibility of a mechanical universe were small solids were in motion. He is seen as the pioneer of physics. -
John Dalton
Completed multiple expirements involving chemicals that proved the presence of lump space particles or atoms.He knew that this was important. Today Dalton's theory is still relevant. It consist of 6 Parts:
Matter is composed of extremly small particles called atoms
Atoms are indivisable and indestructable
Atoms of a given element are identical in size,mass and chemical properties
Atoms of specific elemnts are different than those of other elements
In a chemical reaction, atoms seperate,etc. -
James Maxwell
Electrcomagnetic field and wanted to show electricity in its most simplest form, side note; he also showed that Saturn rings are individual atoms. He derived equipartition theory. -
Heinrich Hertz
A German physicist who completed a famous expirement called the Photoelectric effect which lead to Albert Einstien rethinking the theory of light. He also worked on electromagnetic induction furthering our knowledge in the relationship wavelength/light with energy. -
JJ Thompson
He conducted expirements with a ray he created to test the polarity of atoms. Hefound most of them were negative particles or beta. he also helped Milikan help determine the charge of an electron at a later date. -
Ernest Rutherford: Alpha and Beta
Rutherford in a NutshellOf the many contributions made by Ernest Rutherford, one of his first was in 1898 when he conducted expirements focusing on the charges of atoms and found the the alpha,beta particle. Rutherford also known for his gold foil experiment -
Max Planck
Developed quanta and the constant h, and the quantum thoery in physics. This theory revolutionized our understanding of atomic and subatomic processes. Its best use today is the developement in quantum computers and technology. -
Albert Einstien
During this time, Albert Einstien created the worlds most famous equation E=mc2, he released a Nobel Peace prize winning essay on the Photoelectric Effect on how light absorption causes the release of electrons. -
Niels Bohr
Came up with a model for an atom and it contained an orbit and shells, we refere to it as a quantum model. This gave us the understanding of how atoms bond and stay the same. -
Gustav Kirchhoff
Kirchhoff along side Bunsen were able to find 50 of the first elements on the periodic table. Alone, Kirchhoff studdied under Newman and worked to come up with the understanding of how electrostatic and electric currents can be combined.
