. If a solution of food coloring of unknown concentration is found to have an absorbance of 0.325 at that wavelength, calculate the concentration of food coloring in the solution.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
