Among the group XIV elements, namely Sn, C, Si, and Ge, their conductive properties differ. Which of the following statements explains this phenomenon?

Options

  1. ASn has a completely filled valence band due to its larger atomic size.
  2. BC possesses a large energy gap of 5.4 eV, making it an insulator.
  3. CSi's energy gap of 1.1 eV places it in the category of a semiconductor.
  4. DGe's energy gap of 0.7 eV allows it to exhibit semiconductor behavior.

Correct answer

B. C possesses a large energy gap of 5.4 eV, making it an insulator.

Step-by-step solution
