Final answer:
The statement is false; Carbon, being to the right of Silicon in the same period of the periodic table, is expected to have a greater electron affinity than Silicon.
Step-by-step explanation:
The statement is false. Silicon (Si) does not generally have a greater electron affinity than Carbon (C) due to its position in the periodic table. In general, electron affinity becomes more negative as you move from left to right across a period. Since carbon is to the right of silicon in the same period, C is expected to have a greater electron affinity than Si.
Additionally, trends indicate that atom size generally increases as you go down a group, so Si, being below C in the same group, is larger. Larger atoms tend to have lower electron affinity because the added electron would be further from the nucleus and less strongly attracted.
