Comparing metals, nonmetals, and metalloids was done in Ms. Ingram's Science class at Baxter. Her students were looking at the characteristics of different elements inside of a Venn Diagram. Which of the following descriptions would best describe the appearance of metalloids?

• Dull

• Powdery

• Shiny

• either dull or shiny

Darrent is working on an investigation of physical properties using samples of metals, nonmetals, and metalloids. He used some wires, a battery, and a bulb to test if each of the samples would be able to complete a circuit causing the

bulb to light up. Next, he shined a bright light on each of the samples. Which physical property is Darrent investigating?

• luster and conductivity

• streak and conductivity

• malleability and hardness

• hardness and luster
