I have to do a search on the development of the different atomic models by scientists such as JJ Thomson, Niels Bohr, James Chadwick and Ernest Rutherford. What were the models developed by these scientists? What is the latest model that has been developed by scientists?
You must have the pictures for all the models.
I will appreciate if you can help me!

JJ Thomson discovered the electron and made a model of the atom the so called ''plumcake'' model vere the electrons were scattered in a body of positive electricity.
Niels Bohr resolved the matter of orbiting electrons.
James Chadwick discovered the neutron explaining some difficulties vith atomi weight of atoms.
Ernest Rutherford explained several matters about radioactivity and the general arrangement of nucleus and electrons.

there is no modek. previously, google the names! Most had something to the xtent of a currant bun...with electrons being the currants. However, the modern model is purely theoretical, with quantatised levels of electrons. Cou can't draw it, yr brain will boggle (i tries once...no good). So yeah, pics of the modern model is impossible..and i have no clue, think it wa Bohr and Rutherford who developed the quantatises models...google the rest!

"on the concept of Rutherford's theories, Bohr revealed his style of atomic structure in 1913, introducing the concept of electrons vacationing in orbits around the atom's nucleus, the chemical houses of the ingredient being quite oftentimes determined by way of the type of electrons contained in the outer orbits. Bohr also presented the concept that an electron might want to drop from a larger-skill orbit to a decrease one, emitting a photon (gentle quantum) of discrete skill. This grew to grow to be a foundation for quantum theory." --------------------------------------... "In 1913 Bohr revealed a theory about the type of the atom in accordance to an in the previous theory of Rutherford's." --------------------------------------... " The frequency of the radiation so emitted might want to be equivalent to the version in skill between those states divided by way of Planck's consistent. This meant that the atom might want to neither soak up nor emit radiation continuously yet in consumer-friendly words in finite steps or quantum jumps. It also meant that the numerous frequencies of the radiation emitted by way of an atom were no longer equivalent to the frequencies with which the electrons moved in the atom, a ambitious theory that a number of Bohr's contemporaries got here upon rather puzzling to settle for. the effects of Bohr's theory, in spite of the undeniable fact that, were shown by way of latest spectroscopic measurements and different experiments. Bohr lower back to Copenhagen from Manchester in the course of the summer season of 1912, married Margrethe Nørlund, and persisted to advance his new attitude to the physics of the atom. The artwork become carried out in 1913 in Copenhagen yet become first revealed in England."

Here, I've done some of your homework for you.
Use this link http://en.wikipedia.org/wiki/Atomic_orbital_model
as your starting point.
I'm sure you'll find what you need.
