Question

the students researched the composition of the shoe materials and discovered the following:

• material a primarily contains carbon (c), hydrogen (h), and oxygen (o)
• material b contains carbon (c), nitrogen (n), and a significant amount of copper (cu)
• material c contains sulfur (s), carbon (c), and a small amount of silicon (si)

based on your knowledge of the periodic table and the properties of these elements, which of the following statements is best supported by the data in figure 1?
carbon is a nonmetal known for improved malleability and ductility.
copper is a transition metal known for its excellent conductivity of electricity and heat.
silicon is extremely responsive due to its large atomic mass and position on the periodic table.
nitrogen is extremely reactive due to its quickly vibrating atoms and liquid state at room temperature.

Explanation:

Step1: Recall element properties

Carbon is a non - metal but is not known for malleability and ductility (metals have those properties).

Step2: Analyze copper

Copper is a transition metal and is well - known for its excellent electrical and heat conductivity.

Step3: Analyze silicon

Silicon's reactivity is not mainly due to large atomic mass. It is a semiconductor with properties related to its valence electrons.

Step4: Analyze nitrogen

Nitrogen is relatively stable at room temperature as it exists as $N_2$ with a triple bond between the two nitrogen atoms.

Answer:

Copper is a transition metal known for its excellent conductivity of electricity and heat.
