The Dalton model
The Dalton model was invented by a British cheist named John Dalton. He figured out that each element is made of atoms that are all the same or alike. He also concluded that every element has atoms of a different mass.

The Thomson Model
A British scientist named J.J Thompson discovered the electron. He then created a model showing that an atom may be made out of a sphere of electrons. His model is siad to look like a muffin with berries.

The Nagaoka Model
Japanese physicist Hantaro Nagaoka DIscovered that each atom has a sphere in the center made up of a posotive energy.

The Rutherford Model
British Physicist Ernist Ruthford concluded that the atom is mostly made out of space that is not used, or empty.

The Bohr Model
A Danish phyisicist Niels Bohr discovered that in each atom electrons cirlce in different layers of the atom. It is resembled as an onion, it has different layers all the way through the core.

Period: to
The Present modern model
The present model shows that electrons form a negativly charges ring around the nucleus. -
The Chadwick Model
British physicist James Chadwick discovered the nuetron. It Showed why the atoms mass is hevier than all the electrons and protons added together.
