• 9 g
• 9 in/g
• 9 mL
• 9 g/mL

Sammy is given an element.  He needs to find out if the object is a metal, nonmetal, or metalloid.  The object has a shiny luster, is a solid, and is a conductor.  Is it most likely a metal, nonmetal, or metalloid?

• metal
• nonmetal
• metalloid

Given the properties in the picture, is aluminum a metal, nonmetal, or metalloid?

• metal
• nonmetal
• metalloid

The mass of the sample of talc was 20 g.  Its volume was 5 cm.  What was the density of the talc?

• 6 g/cm³
• 5 g/cm³
• 4 g/cm³
• 3 g/cm³

Mark studied an element was silver-gray, solid, and magnetic.  What category would it fit in?

• metalloid
• nonmetal
• metal

Denise learned that if an element has a dull or shiny luster and conducts heat better than a nonmetal, but not as well as a metal, it is a _____________.

• metal
• metalloid
• nonmetal

Zach was learning about metals, nonmetals, and metalloids.  He had the element copper, which had a high luster, was malleable, and ductile.  Was Zach's element a metal, nonmetal, or metalloid?

• metal
