Visualizing Concepts

As discussed in the text, we can draw an analogy between the attraction of an electron to a nucleus and the act of perceiving light from a lightbulb—in essence, the more nuclear charge the electron “sees,” the greater the attraction. (a) Using this analogy, discuss how screening by core electrons is analogous to putting a frosted-glass lampshade between the lightbulb and your eyes, as shown in the illustration.

(b) Explain how we could mimic moving to the right in a row of the periodic table by changing the wattage of the lightbulb. (c) How would you change the wattage of the bulb and/or change the frosted glass to mimic the effect of moving down a column of the periodic table?[Section]
