Quantum Mechanics and Electron Behavior

These flashcards cover key concepts discussed in the lecture on quantum mechanics and electron behavior, including quantum numbers, the Schrodinger equation, and electron probability.

Quantum Numbers

Values that describe the unique quantum state of an electron, including its energy level, shape, and orientation.

Principal Quantum Number (n)

Indicates the size and energy of the orbital, represented as positive integers (1, 2, 3, …).

Azimuthal Quantum Number (l)

Describes the shape of the orbital; can take values from 0 to n-1, corresponding to s (0), p (1), d (2), f (3) orbitals.

Magnetic Quantum Number (ml)

Specifies the orientation of the orbital within a given subshell; can take values from -l to +l.

Spin Quantum Number (ms)

Indicates the spin of the electron, can be +1/2 (up) or -1/2 (down).

Schrodinger Equation

A fundamental equation in quantum mechanics that describes how the quantum state of a physical system changes over time.

Wave Function (Ψ)

A mathematical function that describes the quantum state of a system; its square gives a probability density.

Node

A point in a standing wave where the amplitude is zero, indicating a 0% probability of finding an electron.

Pauli Exclusion Principle

States that no two electrons can have the same set of four quantum numbers.

Diffraction Pattern

A pattern formed when waves, such as electrons, spread out after passing through a narrow aperture.

Interference Pattern

A pattern resulting from the overlap of two or more waves, leading to regions of constructive and destructive interference.

Orbitals

Regions in an atom where there is a high probability of finding electrons; characterized by distinct shapes (s, p, d, f).

Emission Spectrum

The spectrum of light emitted when electrons transition between energy levels and release energy as photons.

Standing Waves

Waves that remain stationary in space, with nodes and antinodes, often used to model electron behavior.
