The Wave Nature of Light
The number of waves that pass a given point per second
What is frequency?
The minimum amount of energy that can be gained or lost by an atom.
What is a quantum?
The lowest allowable energy state of an atom
What is the ground state?
The element's symbol surrounded by dots representing all of the atom's valence electrons.
What is an element's electron-dot structure?
The arrangement of electrons in an atom is called this.
What is the electron configuration?
The highest energy electromagnetic waves currently known to mankind.
What are gamma rays?
Electrons call photoelectrons are emitted from a metal's surface when light at or above a certain frequency shines on the surface.
What is the photoelectric effect?
Bohr assigned this to each orbit/energy level in a hydrogen atom.
What is a quantum number?
This is an example of it.
[Ne]3s^1
What is Noble-gas notation?
Single electrons with the same spin must occupy each equal-energy orbital before additional electrons with opposite spins can occupy the same orbitals.
What is Hund's rule?
The lowest energy type of electromagnetic wave.
What is a radio wave?
A massless particle that carries a quantum of energy.
What is a photon?
It is fundamentally impossible to know precisely both the velocity and position of a particle at the same time.
What is the Heisenberg uncertainty principle?
The speed of light in a vacuum = wavelength x this
What is frequency?
A maximum of two electrons can occupy a single atomic orbital, but only if the electrons have opposite spins.
What is the Pauli exclusion principle?
As frequency and energy increase, wavelength does this.
What is decreases?
He proposed in 1905 that a beam of light has wavelike and particlelike properties.
Who is Albert Einstein?
A three-dimensional region around the nucleus which describes the electron's probable location.
What is an atomic orbital?
h in the particle electromagnetic-wave relationship equation
What is Planck's constant?
Each electron occupies the lowest energy orbital available.
What is the aufbau principle?
A form of energy that exhibits wavelike behavior as it travels through space.
What is electromagnetic radiation?
The set of frequencies of the electromagnetic waves (various colors) emitted by atoms of the element.
What is atomic emission spectrum?
The atomic model in which electrons are treated as waves; this model which is called the wave mechanical model is also known as this.
What is the quantum mechanical model of the atom?
The numerical value of Planck's constant
What is 6.626 X10^-34 Joules?
These electrons determine the chemical properties of an element.
What are valence electrons?
