We can draw an analogy between the attractions of an electron to a nucleus and seeing a light bulb-in essence, the more nuclear charge the electron "sees," the greater the attraction.
(a) Within this analogy, discuss how the screening by core electrons is analogous to putting a frosted-glass lampshade between the light bulb 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 light bulb.
(c) How would you change the wattage of the bulb and/or the frosted glass to mimic the effect of moving down a column of the periodic table?
