Chemistry Chapter 5 Test Flashcards
Atomic orbital
A mathematical expression describing the probability of finding an electron at various locations
Photon
A quantum of light
Pauli exclusion principle
An atomic orbital may describe at most two electrons, each with opposite spin direction
Hund’s Rule
Electrons may occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible
Electromagnetic radiation
Includes radio waves,microwaves,infrared waves, visible light, ultraviolet waves, X rays and gamma rays
Heisenberg uncertainty principle
It is impossible to know exactly both the velocity and the position of a particle at the same time
Quantam
The amount of energy needed to move an electron from one energy level to another
Electron configurations
The arrangement of electrons of an atom in its grand state into various orbitals around the nuclei of atoms
Wavelength
The distance between adjacent crests of a wave
Amplitude
A height of a waves crest
