Atom Model Experiments Contribution To Atom Model

Front 1

Billibard Model

Back 1

In the belief of the fact that all matter is made of particles which in turn are made of atoms, this model was used to descibe the inseperable indestructible model of a atom, considering his belif that particles have unique roperties that cannot be divided.

Cathode Ray Tube

Back 2

the use of magnets to direct the light gave way to the theory that there are both positive and negative charges to make up atoms ( electrons and protons) due to the reaction of the energies particles.

Front 3

the Plum- pudding Model

Back 3

Using the findings of William Crookes Cathode Ray Tube experiment the conclusion was that the protons and electrons were all jumbled together in the same space in the original sphere idea of John Dalton.

Front 4

Gold Foil Experiment

Back 4

Tiny high-speed particles shot through the gold foil didn't all pass through some bounced off or changed courses while passing through the particles giving the idea that the protons and electrons are in a small centre space of the atom surrounded by lots of space in order to get the particles specific reaction and direction.

Front 5

Bohr and Flame Test

Back 5

This experiment added energy to hydrogen and the same 4 light mixture was given off those atoms. This made Bhor realize that the particles, when excited emitted a special "fingerprint" and then the electrons would return to their ground state. This made Bhor change the model to electrons orbiting the nucleus rather than just clouding around it.

Front 6

Chadwick and the neutron

Back 6

The current atom model we use today was compiled of all prior experiments proved that there is a neutral part of the atom mixed with protons and surrounded my space and being orbited by electrons, this non-electrically charged subatomic particle being called the neutron.
