Q1) Equation 4 above gives the energy per hydrogen atom. The energies will be easier to work
with if we consider a mole of atoms. Fill in the equation below, converting the constant
(-2.178x10-18
-18J/atom) to units of kJ per mole. Check your answer with your instructor by
email before you proceed! (Hint: If the energy is -2.178x10-18 J for one atom, will the energy
become bigger or smaller for a mole of atoms? More negative, or less negative?)

Q2) Theoretically, an atom has an infinite number of energy levels. However, we will focus on the
first ten. Using the equation you determined in Question 1 above (giving k) per mole of atoms),
complete the following table. These energies correspond to the energy of an electron in a particular
energy level.

B. Calculation of the wavelengths of the lines in the hydrogen spectrum
The observed light emitted by hydrogen is due to the transitions of electrons in hydrogen atoms
from higher energy levels to lower energy levels. Therefore, the energy of the photons is calculated
n (lower)
Ephoton = |AE| = |Efinal - Einitial|
To complete the upper half of each box, use the values of E calculated in Table 1 to find the change
in energy using the equation above. For example, the AE for an electron going from the second
energy level to the first is -328- (-1312) = 984. Do this for all the upper halves of the boxes. The
lower half of each box is explained below.
To complete the lower half of each box, calculate the wavelengths associated with the energy
changes that were calculated in the upper half of the box.
