Chapter 5 Vocab Flashcards
An atomic orbital may describe at most two electrons each with opposite direction
Pauli exclusion principle
The amount of energy needed to move an electron from one energy level to another
Quantum
Energy waves that travel in a vacuum at a speed of 2.98×10{8th} m/s; includes radio waves, microwaves, infrared waves, visible light, ultraviolet waves, x-ray waves, gamma rays
Electromagnetic radiation
The number of wave cycles that pass a given point per unit of time; frequency and wavelength are inversely proportional to each other
Frequency
The quantum of light, a discrete bundle electromagnetic energy that interacts with matters similarly to particles
Photon
The specific energies an electron in an atom or other system can have
Energy level
The arrangement of electrons of an atom in its ground state into various orbitals around the nuclei of Atoms
Electron configuration
When electrons occupy orbitals of equal energy, one electron enters each orbital until all orbitals contain one electron parallel spins
Hund’s Rule
The height of a waves crest
Amplitude
The unit of frequency, equal to one cycle per second
Hertz
The lowest possible energy of an electron described by quantum mechanic
Ground state
Electrons enter orbitals of lowest energy first
Aufbau Principle
The portion of the electromagnetic spectrum that is visible
Visible spectrum
The distance between two crests
Wavelength
The pattern formed when light passes through a prism or diffraction grating to separate it into a different frequency of light it contains
Atomic Emission Spectrum
