The Nature of Light
The number of waves that pass by a point in a given time
frequency
This model of the atom described electrons as moving about the nucleus in specific orbits called energy levels
Bohr model
This quantum number indicates the shape or type of subshell in which an electron is found
azimuthal
The region of space through which an electron moves with probabilities determined using the Schrodinger equation
orbital
The idea that light consists of a series of waves rather than individual particles
wave theory of light
He first proposed that light is composed of matter waves
Louis de Broglie
This quantum number indicates the main energy level in which an electron is found
principal
SI unit of frequency
hertz
The tiny bundles of energy that make up light
photons
This idea states that it is impossible to simultaneously determine the momentum and the position of an electron with certainty
uncertainty (Heisenberg) principle
This quantum number differentiates two electrons occupying the same orbital
spin quantum number
This property of a wave is equal to half the vertical distance between a crest and a trough
amplitude
This theory states that light consists of tiny "packets" of energy called photons
quantum theory
This property of atoms causes electrons to produce line spectra instead of continuous spectra
quantized energy levels
According to this principle, the maximum number of quantum numbers that two electrons in the same atom can share is three
Pauli exclusion principle
This scientist showed that a light wave can be accurately described as an electromagnetic wave, an electric field and a magnetic field vibrating at right angles to each other
James Clerk Maxwell
Because light exhibits wave-particle duality is the best reason why the quantum theory of light replaced this theory
wave theory of light
Both absorptions and emissions involve transitions between specific energy levels. Because of this, they are both ____.
quantized
This principle states that electrons occupy the lowest-energy orbital available, filling in orbitals of successively higher energies until all the electrons are distributed
aufbau principle
These electrons are drawn in a Lewis symbol
valence electrons
