===About the Borh Model===
: The [[Bohr Model]] was developed by [[Neils Bohr]] following observations that [[electron]]s could gain or lose specific amounts of [[energy]] with the [[Absorb (Physics)|absorption]] and [[Emit|emission]] of light. This suggested that there were specific [[Energy Level]]s that [[electron]]s could be in. If an [[electron]] [[Absorb (Physics)|absorbs]] [[light]] it can move to a higher [[Energy Level|energy level]] and when it falls back to a lower [[Energy Level|energy level]] the [[electron]] will [[emit]] an [[electron]].
: These [[Electron Energy Level|energy levels]] are also referred to as [[Electron Orbital]]s and [[Electron Shell]]s.

: The [[Bohr Model]] was updated after the discovery of the [[neutron]] in 1932 by [[James Chadwick]]. The new version of the model included the [[proton]]s and [[neutron]]s within the [[nucleus]].
