Chapter 4-electron Arangement Flashcards
(27 cards)
The emission of a continuous range of frequencies of electromagnetic radiation
Continuous spectrum
A form of energy that exhibits wavelike behavior as it travels through space
Electromagnetic radiation
All the forms of electromagnetic radiation
Electromagnetic spectrum
A state in which an atom has a higher potential energy that it has in its ground state
Excited state
The number of ways that pass a given point in a specific time, usually one second
Frequency
The lowest energy State of an atom
Ground state
A series of specific wavelengths of emitted light created when the visible portion of the light from excited atoms is shined through a prism.
Line emission spectrum
The emission of electrons from a metal when light shines on the metal
Photoelectric effect
A particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy
Photon
The minimum quantity of energy that can be gained or lost by an atom
Quantum
The distance between corresponding points on adjacent waves
Wave length
The quantum number that indicates the shape of the orbital
Angular momentum quantum number
It is impossible to determine simultaneously both the position and velocity of an electron or any other part
Heisenberg uncertainty principle
The quantum number that indicates the orientation of an orbital around the Nucleus
Magnetic quantum number
A three dimensional region around the nucleus that indicates the probable location of an Electron
Orbital
The quantum number that indicates the main energy level occupied by the electron
Principal quantum number
A mathematical description of the wave properties of electrons and other very small particle
Quantum theory
A number that specifies the properties of atomic orbitals and the properties of electrons in orbitals
Quantum number
The quantum number that has only two possible values, +1/2 And -1/2, which indicates the two fundamental spin states of an electron in an orbital.
Spin quantum number
An electron occupies the lowest energy orbital that can receive it
Aufbau principle
The arrangement of electrons in an atom
Electron configuration
The electron-containing main energy level with the highest principal quantum number
Highest occupied level
Orbitals of equal energy are each occupied by one electron before any orbital is occupied by second electron and all electrons in singly occupied orbitals must have the same Spin
Hund’s rule
An electron that is not in the highest occupied energy level
Inner shell electron
