10 Cards in this Set

  • Front
  • Back
James Clerk Maxwell
Proposed light is composed of electromagnetic waves.
Max Planck
hot bodies radiate electromagnetic energy whilst he did an experiment using iron bars that changed colors. He also established that hot bodies radiate only discrete numbers.
Albert Einstein
Accounted for photoelectric effect by using light as particles, called photons.

theory of special relativity:

The laws of science should be the same for all freely moving observers regardless of the speed.
Neils Bohr
Neils explained the emission spectrum of hydrogen atom based on the quantization of hydrogen energy. Light is separated in component frequencies when passed through a prism, orbitals were allowed, quantum condition.

Balmer Series are hydrogen lines that are visible.
Louis Victor de Broglie
He figured if light have particular properties, wouldn't particles have wave-like reactions in nature?

wave/part duality
He theorized the less massive the object, the longer the wavelength
Werner Heisenberg
Uncertainty Principle: He thought that the position and momentum of an electron is impossible to be simultaneously determined.
Erwin Schrodinger
Wave (quantum mechanics) Attacks atomic structure by emphasizing wave-like characteristics of electrons. The square of the schrodinger equation gives us the probability of finding the electron in a certain region of space.
Pauli Exclusion principal
only 2 electrons per orbital (no such thing as same four quantum numbers)
Aufbau Principle
Occupies lowest energy first
Hund's Rule
Each orbital is single occupied before double occupied.
