1) How many photons are emitted during a transition from a higher level orbit to a lower level orbit? a)1 b)2 c)3 d)4
2) True/False? An electron can transition from any allowed orbit to any other allowed orbit.
3) What is the wavelength of light emitted when an electron drops from the 3 to the 2 shell in a hydrogen atom?
1. E = E2-E1 =n hV
E = nhV n =1,2,3 ....
E2-E1 = hV
n=1
a.1 answer
2 . True
electron transition from higher energy level to lwer energy level and lower energy level to higher energy level.
3. 1/ = RH[1/n12 -1/n22]
1/ = 109677[1/22 --1/32]
= 109677[0.25-0.11]
= 109677*0.14
= 15354.78 = 6.5*10-5 cm
