Definition for Excitation
Atom Absorbs Energy Because of an Electron Moving From an Inner to an Outer Shell
Definition for Ionisation
Where an Atom Takes in or Release Electrons to Form Positive/Negative Ions
Equation for Energy of An Emitted Photon
E = hf = E1 - E2
Process of Fluorescense (Fluorescent Tube)
- Ionisation and Excitation of Mercury Atoms Occur as They Collide With Electrons Which Have Been Accelerated
- The Mercury Atoms Emit UV Photons and Photons of Much Less Energy
- The UV Photons are Absorbed by Atoms in the Fluorescent Coating Causing Excitation of the Atoms
- These Atoms De-Excite in Steps and Emit Visible Light Photons
