Atomic Emission Spectra and the Bohr Model
Excited State
A state in which an atom has a higher potential energy than it has in its ground state
Spectroscope
An instrument that separates light into a spectrum.
Emission Spectrum Lines
Emission Spectrum Lines occur when the electrons of an excited atom, element or molecule move between energy levels, returning towards the ground state.
Ground State
The lowest energy state of an atom
The Bohr Model
model of the atom in which electrons move rapidly around the nucleus in paths called orbits
Quantum
the amount of energy required to move an electron from one energy level to another.
Energy Levels
the fixed energies an electron can have.
Atomic Emission Spectrum
the pattern formed when light emitted by an element is separated into the different wavelengths it contains.
Niels Bohr
the young Danish physicist who proposed an atomic model that described electrons as moving in circular orbits around the nucleus.
