8. (4 pts. total; 2 pts. each) In the space provided below, explain the following atomic properties. Be succinct. Electronegativity (X^) Polarizability 9. (4 pts) Trifluoroacetic acid (CF3CO2H: pK = 0.23) and acetic acid (CH3CO2H; pk= 4.75) are monoprotic acids (meaning they can dissociate only one H ion/molecule of acid). Using your knowledge of structure, explain why the acid dissociation (Ka) of acetic acid is greater than that for trifluoroacetic acid. Place your answer...

Problem 2 (20 pts) A scanning tunneling microscope employs a small sharp conducting tip that is brought into close proximity of a material, as TIP shown in the figure at right. The vacuum region between the tip and the sample acts as a potential barrier because the electrons in the material have a lower potential than in free space (work functions of the materials). Therefore, the current across the vacuum is proportional to the transmission probability T approximated by a...
