==Key Stage 4==
===Meaning===
'''Energy Levels''' are another name for the [[Electron Shell|electron shells]] or [[Electron Orbital|orbitals]] around the [[Atomic Nucleus|nucleus]] where [[electron]]s can exist.
===About Energy Levels===
: The existence of '''energy levels''' in [[atom]]s is part of the [[Bohr Model|Bohr model of the atom]].
: The [[Electron Orbital|electron orbital]]s in [[atom]]s each correspond to [[electron]]s with a certain amount of [[energy]], which is why they are also called '''energy levels'''.
: [[Electron]]s cannot exist anywhere between the '''energy levels''' they can only exist in one '''energy level''' or another.
: In [[chemistry]] [[electron]]s are seen as fixed in their '''energy levels''' but in [[physics]] the [[electron]]s can move to a higher '''energy level''' by the [[Absorb (Physics)|absorption]] of [[energy]] and can drop down into an empty '''energy level''' below by [[emit]]ting [[energy]].
: The [[wavelength]]s of [[electromagnetic Wave|electromagnetic wave]] depend on the [[energy]] difference between the [[Energy Level|energy levels]] in [[atom]]s.
