Sorry, I did not have time to scan a picture of the orbital. It
looked like a hula hoop

peanut.

For the following questions, refer to the diagram of the orbital shown
to the right (see

above note).

1. Is this orbital an s, p, d, or f orbital?

2. Pictures of orbitals such as this one are often drawn as having a
smooth, distinct

shape. Is this smooth shape accurate? If not, explain what
the shape represents.

3. Complete the following orbital energy diagram up to and including the 4f orbital:

1s_, 2s_, 2p_ _ _, etc....

4. Write electron configurations for the following elements:

A. C

B. P

C. Se

5. How many unpaired electrons are their in the element nitrogen?

6. How many electrons are there in the highest occupied energy level of Se atom?

7. What is the maximum number of electrons that can fit into the third
energy level of

an atom?

8. is the following atoms in its ground state? Explain?

1s^{2} 2s^{2} 2p^{5}
3s^{1}

9. Which of the following colors of light has the highest frequency: red or blue?

10. Which of the following colors of light has the longest wavelength: red or blue?

11. A surfer catches a wave with a frequency of 1.0 Hz. If the
wavelength of this wave

is 4.3 meters, what is the speed of the wave?

12. What is the energy of a wave that has a frequency equal to 5.3 x
10^{14} Hz?

13. If atom A shown to the right had an electron that dropped from the
3p orbital to the

2s orbital, calculate the following.

3p -- 9.5 x 10^{-19} -- 3s -- 1.7 x 10^{-18} --
2p -- 3.8 x 10^{-18} -- 2s -- 1.5 x 10^{-17} -- 1s

A. The energy of the photon of light emitted.

B. The frequency of light emitted.

C. The wavelength of light emitted.

14. Could the atom shown to the right absorb a light photon with an
energy of 2.0 x

10^{-17} J? explain.

15. Atoms are such small objects, and yet every atom could be said to
occupy an

infinite amount of space. Explain how this can be possible.

16. When two different elements are heated, they each give off different
colors of light.

A. Describe why light is given off from an atom when it
is heated?

B. Why are the colors of light given off from one atom
different from another?
