Question

A student tested the conductivity of four elements using an incomplete electrical circuit. When the element is placed in the circuit, the bulb lights up brightly, lights up dimly, or does not light up at all based on the element’s ability to conduct electricity. The table below shows the results of her investigation. Based on the results of the conductivity test, which element is classified as a metal?

Answer 1

Based on the results of the conductivity test, copper is classified as a metal.

Copper is the only element among the four that exhibits the characteristic property of a metal, which is to conduct electricity well.

In this case, copper causes the bulb to light up brightly, indicating strong conductivity.

Aluminum, sulfur, and silicon, on the other hand, do not conduct electricity well, as evidenced by the bulb either lighting up dimly or not at all.

Therefore, copper is the only element among the four that exhibits the characteristic property of a metal.
