As a light wave's wavelength decreases, its energy ________.
Emission of electrons from metals illuminated by light of an appropriate wavelength
Wave - Particle Duality
The notion that in some situations, light is best described as a wave, whereas in other cases, it is better described as a particle
a particle of light
The energy of a photon of orange light is _____ than that of a photon of red light.
The pattern of wavelengths of light absorbed or emitted by a particular element
All elements display _______ spectra, emitting only certain wavelengths of light.
When light is emitted, an atom goes from a _______ energy state to a _______ energy state.
An atom goes from a energy higher state to a lower energy state
when light is emitted.
A state formed when an atom or molecule absorbs energy, as when an electron is promoted to a higher energy orbital
The lowest energy state of an atom or molecule
Electrons _____ energy when they return to a lower energy state.
In the Quantum Mechanical Model of the atom, electrons are viewed as _______ rather than as particles.
The principal quantum number (n) defines the _______ in which a particular orbital is found.
The secondary quantum number specifies ________, smaller groups within a shell.
A plane in which there is no probability of finding an electron
The Uncertainty Principal
This principal says that it is impossible to determine both the position and momentum of an electron simultaneously and with complete accuracy.
The Pauli Exclusion Principal
This principal states that no two electrons in an atom may have the same set of four quantum numbers
If two electrons occupy the same orbital, they must be _____ ________.
The masking of the nuclear charge by other electrons. Electrons in an orbital interact with other electrons, and not just with the positively charges nucleus.
