The flashcards below were created by user anitaebrahimi on FreezingBlue Flashcards. What would you like to do?


  1. wavelength of visible light
    700 nm - 400 nm

      700   R O Y G B I V  400
  2. electromagnetic spectrum in order, and energy wavelength frequency thing
  3.           R M I V U X G
    • low energy               high energy
    • long wavelength       short wavelength
    • low frequency           high frequency
  4. c=? (nm/s and m/s)
    • c= 3.0x108 m/s
    • c= 3.0x1017 nm/s
  5. ground state
    where the arrow is pointing at
  6. excitation absorption
    arrows pointing up
  7. Relaxation emittion
    the arrows pointing doowwnnn
  8. description of S P D F
    • s- sphere
    • p= hourglass
    • d- clover/flower
    • f- starburst
  9. sublevel orbitals for spdf
    • s= 1
    • p=3
    • d= 5
    • f=7
  10. energy sublevel
    #e- = 2(n2)
  11. If you have a valence electron of 3 and under.....
    • you give it to another valence electron that needs it..
    • so ex. 3 valence electron will give it to 5 valence to make a full 8
    • this means +3
    • making it smaller
  12. if you have a valence electron of 5 and higher....
    you gain electrons from an outside thing.. so if u have

    • 6 valence u gain 2, meaning -2
    • making the atom larger
  13. if you want to skip a bunch of that configuration stuff you start with a noble gas..
    also don't forget....
    brackets around it

    ex. [xe] 6s2...
  14. periodic trends
    left to right--->> decreasing size and increasing ionization

    up to down --->> increasing size and decreasing ionization
  15. nuclear symbol
  16. Proton = atomic number
    proton+ neutron = mass
    (unless its an ion, then its electron and neuron= mass)
    highest energy electron are usually the last ones

    and valence are the left overs
