==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.

: If an [[electron]] in an '''energy level''' gains enough [[energy]] it can leave the [[atom]] completely so they [[atom]] becomes a [[Positive Ion|positive]] [[ion]].

		+	===Meaning===
		+	'''Energy levels''' are the discrete amounts of [[energy]] that [[electron]]s in an [[atom]] can have.
		+
		+	===About Energy Levels===
		+	*[[Electron]]s occupy specific [[Energy Level\|energy levels]] or [[Electron Shell\|shells]] around the [[Atomic Nucleus\|nucleus]].
		+	*When an [[electron]] absorbs [[energy]], it can move to a higher '''energy level''' ([[Excited\|excitation]] in which the [[atom]] is said to be [[excited]]. NB: not the [[electron]] itself).
		+	*When an [[electron]] falls to a lower '''energy level''', it [[emit]]s [[energy]] in the form of a [[photon]].
		+	*The [[energy]] difference between '''levels''' determines the [[frequency]] of the [[emit]]ted or absorbed [[photon]].
		+	*'''Energy levels''' are quantized, meaning [[electron]]s can only exist in these specific levels and not in between.
