Back

de Broglie

Front

Equation treating electron as a wave

Back

Schrodinger

Front

Why can't we know the electron's position and momentum?

Back

The electron's mass is too small.

Front

Position & momentum of an electron cannot be known simultaneously.

Back

Heisenberg

Front

Why is Bohr's planetary model not used today?

Back

Too specific; we cannot know the electron's exact location.

Front

No two elements share the same line spectrum.

Back

True

Front

Difference between Quantum Mechanical Model and Bohr's model?

Back

The QMM shows the probability of the electron's location.
