link to Chemistry gateway, which contain links to videos about various chemistry concepts - you'll have to find the relevant specific link(s) to do this assignment.

on a sheet of paper, (i) answer the below questions based on your textbook and the above video link, (ii) include textbook page number(s) and url of the website (or sequence of links starting from the above link), where you found the answer, and (iii) include the names of all group members and identify the recorder.

topic(s): quantum model: atomic orbital

questions [16 points; 2 points / question]

1. compare the Bohr model of an atom versus the quantum model of an atom; i.e. what's the difference bewteen an 'electron orbit' versus 'electron orbital' (or atomic orbital) ?

2. simulation to visualize atomic orbitals. you may use your mouse to rotate the image, i.e. to visualize the AO from a different perspective. if the simulations are unavailable, then you'll have to just read the textbook and listen / view the videos.

site 1 (alternative; requires either cdf player plug-in or Mathematica)

a. what is the orientation of various p AO with respect to the x-, y-, and z- axis ?

b. what is the orientation of d AO with respect to the x-, y-, and z- axis ?

site 2 (sofware on school server: student menu -> science application)

c. what is the relative difference in size between 1s, 2s, and 3s AO ? 2 p versus 3p AO ?

d. what does the density of dots represent ?

3. what are 'quantum numbers' and describe how they relate to a description of an atomic orbital ?

4. what is electron spin ? what is a consequence of electron spin in regards to the maximum number of electrons in of an orientation of an atomtic orbital's ?

5. based on the preceding information, determine the total maximum number of electrons in an atomic orbital.
