What is this?

Quantum Mechanical Model/"Electron Cloud" Model

100

In 1924, this scientist proposed that all matter exhibits wave-like properties.

Louis de Broglie

100

Proposed the idea of this surrounding the nuclei of atoms that stated the locations of electrons based on energy levels and probability instead of certainty.

Electron Cloud

100

This experiment critiques the quantum theory and how people believed it worked at the time.

Schrödingers Cat Experiment

200

When was this model created?

What is 1926?

200

What was he significant for?

Describing electrons as matter waves.

200

Instead of explaining electrons as particles, he explained them as this:

Waves

200

He won a Nobel prize in physics for discovering new forms of the atomic theory in this year.

What is 1933?

300

The mechanics of this mathematical equation explained why atoms have discrete, quantized energy levels and how electrons energy can be determined.

Schrödinger's equation/the wave equation

300

He based the model of his atomic theory off of these two scientists established model- but would go on to adapt the unproven parts of the model into mathematically derived functions that explained why the model appeared as so.

Who are Niels Bohr and Arnold Sommerfeld?

300

Instead of traveling in neat, flat lines, Schrödinger proposed electrons occupy three-dimensional spaces commonly known as these.

Orbitals/shells

300

Every scientist who outlined this theory prior stated that you could pinpoint locations of electrons approximately.
