Electron Theory Pdf Atomic Nucleus Atoms Elements are made of tiny particles called atoms. atoms of one element are identical while atoms of different elements are different. different atoms form compounds in constant ratios. the structure of atoms is somehow related to electricity. discovered atoms have negative particles (electrons) using a cathode ray tube. uniform positive charge. The paper outlines the historical development of atomic theory, tracing the evolution from democritus's early ideas to modern models proposed by scientists like dalton, thomson, rutherford, and bohr.
Atomic Theory Pdf Atoms Electron The document summarizes the development of atomic models from ancient greek philosophers to modern physics. it describes early atomic theories proposed by democritus and dalton, followed by discoveries of the electron by j.j. thomson and the nuclear model from rutherford's gold foil experiment. In 1913, proposed the bohr model, which suggests that electrons travel around the nucleus of an atom in orbits or definite paths. "bohr theory of the atom" was the closest to the modern atomic theory, and it reemphasized the idea of electrons circling the nucleus. bohr suggested that electrons orbited around the nucleus in seven different quantum levels, or shells. He noticed that these were the subatomic parts of the atom and he believed atoms had a structure similar to plum pudding with negatively charged electrons embedded in a positively charged underlayer.

Bohr’s atomic model (aka the rutherford bohr model) electrons orbit the nucleus in orbits that have a set size and energy. the lower the energy of the electron, the lower the orbit. this means that as electrons fill up the orbitals, they will fill the lower energy level first. Democritus gives atoms the name ‘atomos’ lived in greece in 4th century bc. he developed a theory of matter based on ‘atomos’ which he des ibed as tiny indivisible particles. his theory was that the atoms that made different materials were physically different from one.
