Which of the following elements displays both metallic and non-metallic properties?AsulfurBphosphorusCcarbonDneon

The element that displays both metallic and non-metallic properties is C. Carbon.

Explanation:

1. Element Properties: Carbon is unique because it has a variety of allotropes that exhibit different properties. For instance, graphite, one of its allotropes, conducts electricity (a metallic property), while diamond is an excellent insulator (a non-metallic property).

2. Metalloids: Elements that exhibit properties of both metals and non-metals are known as metalloids. Carbon, while generally categorized as a non-metal, can show metallic characteristics under certain conditions, particularly when it comes to its bonding and conductivity in specific structures.

3. Comparison with Other Options:

   • A. Sulfur: Primarily a non-metal.
   • B. Phosphorus: Primarily a non-metal with some metalloid properties.
   • D. Neon: A noble gas with non-metallic properties.

Overall, carbon stands out for its versatile bonding and structural properties.
