Atomic Emission Spectrum
the pattern formed when light passes through a prism or diffraction grating to separate it into the different frequencies of light it contains
a mathematical expression describing the probability of finding an electron at various locations; usually represented by the region of space around the nucleus where there is a high probability of finding an electron
energy waves that travel in vacuum at a speed of 2.998 x10^8 m/s; includes radio waves, microwaves, infrared waves,visible light, ultraviolet waves, x-rays, and gamma rays
the arrangement of electrons of an atom in its ground state into various orbitals around the nuclei of atoms
Heisenberg Uncertainty Principle
says it is impossible to know exactly both the velocity and the position of a particle at the same time
electrons occupy orbitals of the same energy in a way that makes the number of electrons with the same spin direction as large as possible
Parli Exclusion Principle
an atomic orbital may describe at most two electrons, each with opposite spin direction
a quantum of light, a discrete bundle of electromagnetic energy that interacts with matter similarly to particles
Quantum Mechanical Model
the modern description, primarily mathematical, of the behavior of electrons in atoms
wavelengths of visible light that are separated when a beam of light passes through a prism, range of wavelengths of electromagnetic radiation
