Quiz #3:
Atomic Levels (Topic 3)
February 21, 2007
Name: ____SOLUTIONS__________
Problem 1
Carefully draw an energylevel diagram for a oneelectron atom of nuclear charge Z=4. Draw the
levels n = 1, 2, 3, and
∞
and write an expression
for the energy levels
. Use arrows to indicate the
following transitions on the diagram: a) longest wavelength transition in the Lyman series, and
b) highest energy transition of the Paschen series. Calculate photon energies emitted in the above
two cases.
