Atomic Structure and Timeline Objectives: Describe the process why which the atomic structure was discovered Describe what an atom is an what makes it up. Identify differences in protons, neutrons and electrons Democritus 400 BC Proposed that matter was composed of tiny indivisible particles Not based...
Atomic theory is the collection of ideas that have morphed over time as more and more information about the structure of the atom has become clearer. The current model, the Electron Cloud Model, has used pieces of information and research from other scientists dating back thousands of years. ...

Cooper arrives back in time and posts the 'ATOM' advertisment. However, with Eternity non-existent, he gets no response. 1945: The deployment of the atomic bomb at the end of WWII nullifyes the Eternity Reality forever, and fixes the entire timeline of man free from the constant changing...
Any water on Earth during the latter part of its accretion would have been disrupted by the Moon-forming impact (~4.5 billion years ago), which likely vaporized much of Earth's crust and upper mantle and created a rock-vapor atmosphere around the young planet. The rock vapor would have con...
-Postulated the nuclear structure of the atom -Theorized that the electrons orbited the nucleus like planets -Proposed dense atomic mass -Received Nobel Prize in 1908 in Chemistry Neils Bohr (1885-1962) -a Danish Physicist -Stated that electrons orbit in set patterns based on energy -Electrons...
Ernest Rutherford known as the father of nuclear physics, developed the theory for the structure of the atom. He used a gold foil experiment, observing the scattering of alpha particles, and demonstrated for the first time the existence of the atomic nucleus. 1913 Bohr improves the atomic model...
