Energy
The formula for calculating energy.
E = hv
Red
Proposed that electrons should be considered waves.
Louis de Broglie
When light shines on a metal and it has enough energy to cause emission of electrons.
The Photoelectric Effect
Quantum
The unit for measuring energy.
Joules (J)
This color has the highest frequency.
Violet
Said that it is impossible to know both the energy and position of an electron at the same time.
Werner Heisenberg
An electron that absorbs energy goes to __________ state.
Excited
These elements have a line emission spectrum exactly like hydrogen.
None--all elements are unique.
Describes mathematically the wave properties of electrons.
Quantum Theory
This comes after red in order of increasing wavelength.
Stated that electrons have a dual wave-particle nature.
Albert Einstein
An electron that emits energy goes to __________ state.
Ground
A particle of electromagnetic radiation that has zero mass and carries a quantum of energy.
Photon
All colors of light travel at this speed.
Speed of light = 3.00 x 10^8 m/s
This comes after violet light in order of increasing frequency.
Ultraviolet
Developed equations that solved for the energy of an electron and its probable location.
Erwin Schrodinger
The problem with Bohr's model of the atom.
It did not apply to atoms with more than one electron.
A region in the atom where there is a high probability of finding electrons.
Orbital
Calculate the energy of a photon of electromagnetic radiation that has a frequency of 9.50 x 10^13 Hz.
E = 6.29 x 10^-20 J
List the colors in order from highest frequency to lowest frequency.
Violet, indigo, blue, green, yellow, orange, red
Created a model of the atom using orbits as paths for electrons with nothing in between.
Neils Bohr
What is the frequency of an electromagnetic radiation with a wavelength of 4.257 x 10^-9m?
v = 7.047 x 10^16 Hz
The wavelength of the typical radar radiation is 3.19 cm. What is the frequency of this radiation?
v = 9.40 x 10^9 Hz
