|
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.
Photons:Hv KE=HV-BE theory of special relativity: e=mc^2 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.
