Daltons Model
Made the billard ball model
Each element had its own atom
Atoms cannot be destroyed or created
In a chemical reaction, atoms link to one another, or separate from one another. -
Thomson's Model
Plum pudding model
Atoms contain electrons
Electrons have small mass and are negative
Rest of the atom is a sphere is positve
Discovered that neon is made up of two different kind of atoms -
Rutherford's model
Made the solar system model
Found out that an atom is mostly empty space with ddense nucleus surronded by negative elctrons
The nucleus is about 100 000 times smaller than an atom -
Bohr's Model
Thought the atom structure was like a solar system
Thought that atoms only were in certain sports around the nucleus
A fast moving eletron would change the magnetic field and which would carry energy away from the electron and slowing it down and it would end up being captured by the nucleus. -
Quantum Model
Atom constructed the same way we see now except there was clouds of different energy levels
Electrons do not move around the nucleus, they move like planets around the sun
It is impossinle to know exact location of an electron
Location is based on energy
More based on math than any of the other ones
