Chapter 5 Sec. 2 Orbitals and Sublevels Worksheet
Answer the following questions as completely as possible.
1. What is an atomic orbital?
2. What do the sublevel designations s, p, d, and f specify with respect to the atom’s orbitals?
3. What is the maximum number of electrons an orbital can contain?
4. What does n represent in the quantum mechanical model of the atom?
5. How many energy sublevels are contained in each of the hydrogen atom’s first 3 energy levels?
6. What atomic orbitals are related to a p sublevel?
7. How are the 5 orbitals related to an atom’s d sublevel designated?
8. Describe the relative orientations of the orbitals related to an atom’s 2p sublevel.
9. How many electrons can be contained in all the orbitals related to an Argon (Ar) atom’s third
energy level?
10. How many orientations are possible for the orbitals related to each of the following sublevels?
a. s
b. p
c. d
d. f
11. CHALLENGE PROBLEM (yes, you need to do this problem): The hydrogen atom’s energy is -6.05 x
10-20 J when the electron is in the n = 6 orbit and -2.18 x 10-18 J when the electron is in the n = 1.
Calculate the wavelength of the photon emitted when the electron drops from the n = 6 orbit to
the n = 1 orbit. The following values may be helpful: h = 6.626 x 10-34 J●s and c = 3.00 x 108 m/s.
You must show your work to get the points.
