Electron+Cloud+Model

The model was created in the 1930s.

__Describe__ your model so that someone else in your class could understand what it means. it shows the electrons that are located around the atom

Compare and contrast your atomic model to past atomic models.

How was your model an improvement over previous understanding of the atom? ~Bohr's model was too simple to __describe__ heavier elements.

//first model//: the first atomic model was proposed by Democritus. He said that element consist of tiny, solid particles that can not be subdivided.
 * compare and contrast**

//current model//: the new electron __cloud__ was founded by Schrodinger and Heisenberg. They said that the electron __cloud__ is a atom with nucleous in the center. They also said that there is many rings that go all around it but not in a certain path. They found electrons, protrons, and neutrons in the atom(positive and negative charges). scientist now have said that an atom can be cut in half to get a quark, which is smaller than an atom.
