1. wavelength
• - λ(lambda)
• - the distance between 2 consecutive wave peaks
2. frequency
• - ν
• - the # of waves that pass a specific point in 1 sec.
• (Hertz)
3.  equals
speed of light
4. equation for speed of light
5.  are directly/inversely proportional?
inversely proportional
• -Plank's constant
•  (Jules)
6. Energy is measured by
Jules(J)
7. What equation connects energy to frequency?
8. What equation connects enery to lambda?
9. E and  are _______ proportional
inversely
10. Balmer's equation
• - n= the orbit in which the electron falls on
• - allows us to calculate the wavelengths of the lines in the visible spectrum
11. What did Bohr conlude from Balmer's equation?
• e's orbit the nucleus at a fixed distance and the orbit's has a dixed energy
•  must absorb a fix amount of energy to tranfer to the next orbit
• thinks like it is like a solar system
12. color from lvl 3 to lvl 2
red
13. color from lvl 4 to lvl 2
blue/green
14. color from lvl 5 to lvl 2
violet
15. When electrons falls into level 2 from any orbit. it will ALWAYS fall in to the _______ wavelengths
visible
16. fall into lvl 1---->
ultraliviolet
17. fall into lvl 5---->
18. quantized
• only certain values are allowed
• orbits can only be in a certain fixed postitions
19. Schrodinger's eqution
• l
• m
• s
20. n(QN)
• tells us size and energy
• allowed values: 1,2,3,4,5.....
21. l(QN)
• 2nd azimothal QN
• tells us shape
• allowed values: 0.......n-1
22. sublevels of l
• s
• p
• d
• f
23. s orbital
• =0
• sperical
• can hold 2 electrons
24. p orbital
• dumbell
• =1
• two nodes don't touch
• a place of zero probability of finding an electron
• can hold 6 electrons
25. d orbital
• double dumbells
• =2
• can hold 10 e's
26. f orbital
• =3
• nest of eggs
• double dumbells
• can hold 14 e's
27. m(QN)
• tells us orientation of the orbitals with the respect to axes
• - magnectic QN
• allowed values: -l......0......+l
28. s(QN)
allowed values:  or -
29. orbital energy diagram
in lowest to increasing enegy level
30. column 1 & 2: QN?
s block
31. column 3-12: QN?
d block
32. column 13-18: QN?
p block except He which is in S block
33. those seperatee bottom electrons: QN?
f block except Thorium and Cesium
34. Abreviated written electronic configuration
labled to prededing noble gas and the number of electrons (including the element from)  to take to go to noble gas
35. corre. to Ionization energy, going down a family....
less energy required to lose electron to gaseous state
36. corre. to Ionization energy, going across a series from left to right....
generally increases because are nonmetals-less reactive
