Though we know today that they can be further divided into protons, neutrons, and electrons, his explanation was revolutionary for that period of time. Bohr Model Bohr's theory begins with Rutherford's picture of an atom as a nucleus surrounded by electrons moving in circular orbits. Democritus did not do any experiments or provide solid evidence for his theory on the atom. In 1911, Ernest Rutherford discovered the nucleus. 2. Democritus' personality was calm, tenacious, and cheerful - hence the name 'laughing philosopher.'. However, unlike Democritus, Dalton was able to prove the existence of atoms.

"A life without festivity is a long road without an inn.". Bohr's model of the atom (ESAAR) There were, however, some problems with Rutherford's model: for example it could not explain the very interesting observation that atoms only emit light at certain wavelengths or frequencies. His atomic model was solid, and stated all atoms differ in size, shape, mass, position and arrangement, with a void exists between them. •Introduction 460-370 B.C He asked if matter could be divided into smaller and smaller pieces forever Ernest Rutherford (1871-1937) He described the structure of atom Neils Bohr (1885-1962) He explained how atomic spectra worked DOMOCRITUS John Dalton (1766-1844) He proposed the Atomic theory of matter based on his experimental . b. Thomson's d. Democritus's _____7. His contribution helped people with understanding the idea of an atom and helped other scientists a further look into the science of the atom and its generic makeup. Though some of his conclusions were incorrect, his contributions were vital. Atoms are solid, homogeneous, indivisible, and unchangeable. The ancient philosopher Democritus (460-370 BC) asserted that matter is made up of very small particles that cannot be broken or divided.
