Scientists

100

Created an atomic model with electrons circling the nucleus. His model is called the Nuclear Model.

Who is Rutherford?

200

Changed Rutherford's model to put electrons on energy levels or orbits. His model is called the planetary model.

Who is Bohr?

300

Created the Plum Pudding Model. This was the first model with electrons.

Who is J.J. Thomson?

400

Created the first atomic model called the solid sphere model.

Who is John Dalton?

500

Stated that electrons do not move in set paths, but in waves. Created the Quantum Model.

Who is Erwin Schrodinger?

Rules

100

The electrons occupy the orbitals of lowest energy first.

What is Aufbau's Principle?

200

It is impossible to know both the velocity and position of an electron at the same time.

What is Heisenberg Uncertainty Principle?

300

An atomic orbital may have at most two electrons. Each spin in opposite directions.

What is Pauli Exclusion Principle?

400

You must fill in one spin direction first then go to other spin direction.

What is Hund’s Rule?

500

Bonus: she is always right

Who is DrT?
