9. The number of emission lines coming from an atom with these 5 energy
levels is:
Fourth excited state ____________________________ 7 eV
Third excited state ___________________________ 6.5 eV
Second excited state ____________________________ 5.3 eV
First excited state ____________________________ 3.7 eV
Ground state _____________________________0.0 eV
b.10
You can count all the transitions as done in Tutorial 1, or you can simply
add the transitions:
There can be 4 "jumps" from HIGHER LEVELS into the ground state, 3 into
the first excited, 2 into the second excited and 1 into the third excited.
That's 4+3+2+1=10 transitions.
