Atomic Structure

Atomic Structure

1. Atomic Spectrum Of Hydrogen

   • E = Energy (Joules)
   • h = Plancks Constant 6.63x10 34
   • When an electron changes energy levels, light of a particular frequency is emitted.
     • Balmer Series

2. Mass Spectrometry

   • Ionisation, Acceleration, Deflection, Detection
   • Can detect elements and compounds
     • Compound is always furthest to the right.
   • Must be ionised

3. Electron Arrangement

   • S, P. D orbitals
     • 4s lower energy than 3d
   • Ionisation Energy
     • Distance from nucleus, Nuclear Charge, Shielding
       • 5 in P orbital is very unstable

4. Mass is always relative to 1/12 of a atom of Carbon 12
