neils bohr
described that each electron inside the atom has a fixed amount of energy that keep the electrons moving around the nucleus within a definite region.
orbital
the region where a particular electron is located.
excited state
when the electrons move at a high state of energy.
ground state
when an electron goes back to the lower energy level.
planetary model
the description of Bohr’s atomic model.
nuclear model
the model presented by Ernest Rutherford.
spectroscope
the analysis showed that the light given off by the vapors of elements can be observed more accurately with an instrument.
electron configuration
the way electrons are arranged around the nuclei of the atom.
mnemonic device
a tool used in remembering the sequencing of energy levels and sublevels.
