Atomic Models

This is the most complete and current model of the atom. It consists of 61 elementary particles. Electrons are located in complex orbitals.

• The "Quantum Mechanical Model" of the atom

• The "Rutherford Model" of the atom

• The "Plum Pudding Model" of the atom

• The "Bohr Model" of the atom

NGSS.HS-PS1-2

This model this model was the first to show a nucleus, consisting of protons and neutron.  Electrons surround the nucleus but are not shown in distinct energy levels. 

• The "Nuclear Model" by Rutherford

• The "Plum Pudding Model" of the atom by Thomson

• The "Quantum Mechanical Modell" of the atom by Heisenberg

• Democritus's model of the atom

NGSS.HS-PS1-8

This model added on to previous models by showing electrons existed at certain "energy levels". It is often called the Planetary Model.

• The "Bohr Model" of the atom

• The "Rutherford Model" of the atom

• The "Plumb Pudding Model" of the atom

• The "Quantum Mechanical Model" of the atom

NGSS.HS-PS1-1

This model was developed after J.J. Thompson discovered electrons, a particle smaller than an atom. Is shows electrons floating freely in a positive space.

• The "Plum Pudding Model" of the atom

• The "Rutherford Model" of the atom

• Democritus's model of the atom

• The "Quantum Mechanical Model" of the atom

What can you conclude from the fact that scientists continue to update the atomic model?

• New information about atoms continues to be discovered

• Old information about atoms is completely useless

• Scientists did not have any information about atoms until a few years ago

• Scientists still have no idea what atoms look like

Ernest Rutherford discovered that atoms were mostly _________________. 

• negatively charged

• positively charged

• electrons

• empty space. 

Idea was of an indivisible particle of matter he called "atomos"

• John Dalton

• Aristotle

• Democritus

• Plato

Who named the positive center of the atom the "nucleus?"

• Democritus

• Dalton

• Thomson

• Rutherford

Who proposed that electrons move around the nucleus in circular orbits?

• Dalton

• Thomson

• Rutherford

• Bohr

What can you conclude from the fact that scientists continue to update the atomic model?

• New information about atoms continues to be discovered

• Old information about atoms is completely useless!

• Scientists did not have any information about atoms until a few years ago

• Scientists still have no idea what atoms look like
