Quantum Model and Electron Configuration Flashcards
What is the name of Rutherford’s atomic model?
Planetary Model or Nuclear Model
What is the name of Bohr’s model? Explain why it led to the conceptualization of quantum mechanical model.
Planetary Model. It explains that atoms consist of definable energy levels where an electron can reside.
Who developed the quantum mechanical model?
Erwin Schrodinger
As the electron orbits, it ______ energy and so orbits closer and closer until it crashes into the nucleus.

What are the limitations of Rutherford’s model?
It can not explain the atomic line spectra of hydrogen.
What is the limitation of Neil’s Bohr model?
Could not give any information about the distribution and arrangement of electrons in the atom.
Who conceptualized quantum?
Max Plank
Who discovered the wave-particle duality of light?
Albert Einstein
What are particles of light called?
Photons
Who discovered that particles of an atom such as electron can be wave?
Louis de Broglie (Wave-particle duality of matter)
What helped describe the electron as a wave?
The Schrodinger equation
These give us an idea of where around the nucleus a particular electron resides.
The Quantum Numbers
What are the three quantum numbers?
n, l, m (l)
N is the ________________
Principal Quantum Number
Describes the energy level or shell of an electron.
