Colored and Colorless Salt SOlutions

I'm trying to do my post-lab for a lab that is trying to get us to figure out if solution color is predictable from its interaction with visible light and the atomic structure of the salt's metal ion. We mixed different nitrates with water and then looked at its color and absorbency. I just want to know how the valence shell electron configurations would effect the color. Iron nitrate is yellow, Cobalt nitrate is red, nickel nitrate is green and copper nitrate is blue. They're all in a row, but I don't know why Zinc is colorless when it is right next to the colorful solutions.

error in units

The units of resistivity don't come out right.

10^-8 Ohm * m
or
m Ohm * cm

the 'm' should be a 'mu', but unfortunately they both look the same in the latin alphabet.
