Which allotropic form of sulfur is capable of conducting electricity: plastic sulfur or amorphous sulfur?
Plastic sulfur can conduct electricity.
Amorphous sulfur can conduct electricity.
Neither form can conduct electricity.
Both forms can conduct electricity.
Option A Plastic sulfur can conduct electricity: This is the correct answer. Plastic sulfur is a unique allotropic form of sulfur that has a rubbery texture and can conduct electricity, unlike most forms of sulfur.
Explanation of incorrect option
incorrect option B Amorphous sulfur can conduct electricity: This is incorrect. Amorphous sulfur is another allotropic form of sulfur that is an insulator and cannot conduct electricity.
incorrect option C Neither form can conduct electricity: This is incorrect. Although amorphous sulfur cannot conduct electricity, plastic sulfur can conduct electricity.
incorrect option D Both forms can conduct electricity: This is incorrect. Only plastic sulfur can conduct electricity, not amorphous sulfur.
