Atomic Model

Which of the following has the atomic models in the correct Chronological order?

• Solid sphere, Plum pudding, Nuclear, Planetary, Quantum Mechanic/Electron Cloud

• Solid sphere, Plum pudding, Nuclear, Quantum Mechanic/Electron Cloud, Planetary,

• Plum pudding, Nuclear, Planetary, Quantum Mechanic/Electron Cloud,Solid sphere

• Nuclear, Planetary, Solid sphere, Quantum Mechanic/Electron Cloud,Plum pudding,

This was the first model of the atom ever proposed. It was simple and described atoms as tiny spheres that could not be broken down into smaller pieces.

• Democritus's model of the atom

• The "Plum Pudding Model" of the atom

• The "Rutherford Model" of the atom

• The "Quantum Mechanical Model" of the atom

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". However it does not accurately show what those levels look like.

• The "Bohr Model" of the atom

• The "Billiard Ball Model" of the atom

• The "Plumb Pudding Model" of the atom

• The "Electron Cloud Model" of the atom

Use the word bank in the picture to answer the questions that follow:

Fill-in the Blank:

The description of the structure of the atom is called the ___.

J.J. Thomson and his plum pudding model provided evidence that an atom...

• is the smallest particle of matter

• contains negatively charged particles

• has an overall negative charge

• has an overall positive charge

NGSS.MS-PS1-1

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
