-First to discover that electrons have separate orbits around the neucleus

-Diccovered the number of the electrons in the outer orbit determine the properties of the atom

-The Bohr model shows that the atom is a small positively charged nucleus with electrons surrounding the nucleus

# data[].attributes.body
Bohr-

~The greatest was the atomic model

~Shows the atom as a small positively change nucleus surrounded by orbited neutrons

problems

~ Multi electron atoms don't have energy levels

~It doesn't predict the relative intensities of spectral lines

Broglie

~electron act like particles and waves like lights

~Waves produce electron set up nergy, frequencies, & waves (electrons = waves)

Einstein-

~determine size of atoms & molecules

~Einstein use statistics & probablitity revolutionsized study of all complex systems

Heisenburg-

~electrons don't travel in neat orbits

~ made electron cloud

Schrondiger-

~used mathematical equations to describe likelihood of finding an electron in certain position

CONTRIBUTIONS FROM DALTON

* atoms obey the law of multiple proportions

* atoms obey the law of conservation

ERRORS WITH DALTON THEORY

*he claims that all atoms have identical mass

*he thought atoms couldn't me made of anything smaller

CONTRIBUTIONS FROM DEMOCRITUS

* he came up with the first official atomic model

*changes in matter are due to changes in the combination of atoms

CONTRIBUTION OF ATOMIC THEORY TO RANDOM SCIENTIST

* Ernest Rutherford advanced the atomic theory by coming up with a new idea of the next

step in the atomic structure.

* Rutherford was known as the father of nuclear physics

*Thompson discovered the electron.

Thomsons Model Of The Atom:

# data[].attributes.attachment_link.description
The plum pudding model is one of several scientific models of the atom. First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model represented an attempt to consolidate the known properties of atoms at the time: 1) electrons are negatively-charged particles and 2) atoms are neutrally-charged.

-The model makes poor predictions regarding the spectra of bigger atoms

-It doesn't predict the relative intensities of spectral lines

-The model does not explain the structure and the hyperfine structure in spectral lines

•jj Thomson atomic theory identifies that electrons inside an atom could show, meaning that atoms were not invisible.

The Rutherford experiment is the one that involves the gold foil being hit by a beam of alpha particles.

~It showed electrons just placed randomly in the atom.

~There is no cloud of positive charge

~There's are protons in the center instead of with a nucleus

• Dalton's theory said: Atoms of the same element have identical properties but, atoms of different elements have different properties.

• Atoms may obey the law of conservation of mass

Rutherford did not take into account that electrons actually have

properties of light.

Joldi, Julia, Camilla : Thomson's Experiment

# data[].attributes.body
Basically Thomson took a cathode ray tube and though there was

nothing inside the tube, electricity occurred. Thomson decided to

prove that the "rays" that emitted from the electron gun were

inseparable from dormant charge, by using a magnetic field.

He found that the beam deflected from the negative side of the magnet

and that the beam was attracted to the positive side of the magnet.

Contributions from Democritus- All matter is made of atoms and atoms cannot be seperated into smaller particles

Contributions from Dalton- Dalton's contribution to atomic research was all matter is made up of atoms and that atoms are indistructable. he also stated that atoms of the same element are identical while different elements are different. atoms also obey the conservation of mass. atoms must also obey the law of multiple proportions. daltons theory did have errors like atoms being made of smaller parts and atoms being visable.

Contribution of Atomic Theory to Random Scientists- Like Robert Boyle, Isaac Newton studied gases, and the possibility of atoms existing. He proposed a basic model of the atom which consisted of a mechanical universe where small solid masses were in motion. He basically believed that there were little tiny pieces of mass swimming everywhere.
