Chemistry, structure and bonding

Front

AufBau Principle

Back

Lowest energy orbitals are occupied first.

Front

Pauli Principle

Back

Only two electrons may occupy each orbital.

Front

Electron Characteristics

Back

Not discrete, no exact size, shape, and position, do not have a fixed orbit.

Front

Wave-Particle Duality

Back

Matter has wave-like properties. Wave function describes the distribution of electrons in terms of time and position.

Front

Heisenberg Uncertainty Principle

Back

We cannot know an electron's exact position and momentum simultaneously. If we know the exact energy, we can't know where it is, but we can determine where it is most probably located.

Front

Spectroscopy

Back

Known exact energy, cannot know exactly where electrons are.

Front

Orbitals

Back

Where an electron of a specific energy is most probably located.

Front

Principal Quantum Number (n)

Back

The number of electron shells. Determines how big the orbital is and how far an electron is from the nucleus.

Front

Angular Momentum Quantum Number (l)

Back

The shape of the orbital. l = 0: s, l = 1: p, l = 2: d.

Front

Magnetic Quantum Number (ml)

Back

The orientation of the orbital. If l = 1, ml = -1, 0, +1.
