The light emitted by an elements through a prism |
|
|
Atomic Orbital |
Region in space where there is a high possibility of finding e- |
|
|
Aufbau principle |
Electrons enter orbitals of lowest energy first and use Aufbau diagram to represent atomic orbitals |
|
|
Electromagnetic radiation |
A form of energy exhibiting wavelike behavior as it travels through space (includes radiowaves, microwaves, visible light, X-rays) |
|
|
Electron configuration |
The arrangement of electrons in an atom, which is prescribed by three rules: the aufbau principle, the Pauli exclusion principle, and Hund’s rule |
|
|
Energy level |
Region around the nucleus where an electron is likely to move |
|
|
Frequency |
The number of waves that pass a given point per unit of time (v=c/the wavelength) |
|
|
Ground state |

|
|
Heisenberg uncertainty principle |
States that it is impossible to know both velocity and the position of particles at the same time |
|
|
hertz (Hz) |
SI unit of cycle second |
|
|
Hund’s rule |
When one electron occupy orbitals of equal energy one electron enters each orbital until all orbital contain one electron with opposite parallel |
|
|
Pauli exclusion principle |
An atomic orbital may hold 2 electrons |
|
|
Photoelectric effect |
That light could be described as a quanta of energy that behave as particle |

h, which has a value of 6.6262x10^-34J*s |
|
|
quantum |
The amount of energy required to move an electron from its present energy level to the next higher one |

Every atom emits light |
|
|
Spectrum |
Light is separated into it’s colors when shown through a prism |
|
|
Wavelength |
Distance between 2 crest |
