Frequency symbol

v

wavelength symbol

y

Speed symbol

c

Planck’s Constant symbol

h

Heisenberg Uncertainty Principal

cannot know exact location and velocity of electrons

Einstein

light has wave-like and particle-like behavior

photon

a specific quantized amount of light

Broglie

matter moves in wave-like patterns

Photoelectric Effect

Light rays move electrons

atomic emission spectrum

occurs from various amounts of energy given off by electrons

ground state

normal, lowest energy position

Quantum

amount of energy needed for electron to move a level

Bohr’s model?

hydrogen atom

Dalton Model

little indestructible marble

Thomson Model

plum pudding

Rutherford Model

Jimmy Neutron-all electrons same level

Bohr Model

Planetary model 2.0-could explain chemical behavior

Quantum Mechanical Model

uses probability shells of electrons

Aufbau Rule

electrons added one at a time from lowest→highest energy

Pauli Exclusion Principle

Two electrons per orbital. Spin

Hund Rule

all orbitals get one before any get a second. “Good mother rule”

Order of Waves lowest→ highest wavelength

radio,microwave,infrared,visible,uv,x-ray,gamma
