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? 

• Hydrogen

• Arsenic

• Krypton

• Copper
