Metals, Metalloids, and Nonmetals Quiz

A group of elements have no luster, have no conductivity, and are brittle. What is the classification of these elements?

• Metals

• Nonmetals

• Metalloids

Which of these is NOT a physical property used to classify metals, nonmetals, and metalloids?

• Texture

• Malleability

• Conductivity

The element sulfur (S) is grouped in the periodic table with the nonmetals. Based on this, what do you know about sulfur?

• It's a poor conductor of electricity.

• It's soft and malleable.

• It has a shiny surface.

A student is trying to decide if an element is a metal or nonmetal. What should the student do?

• Find the element's density.

• Find the element's melting point.

• Measure the element's conductivity.

Where on the Periodic Table are the metalloids found?

• on the left side

• along the bottom

• between the metals and the nonmetals

What are the physical properties we use to classify metals, nonmetals, and metalloids?

• reactivity, smell, and density

• physical state, hardness, and mass

• luster, conductivity, and malleability

A certain element, when pounded with a hammer, doesn't break apart but forms thin sheets. It also conducts electricity very well. The element is most likely a:

• metal

• nonmetal

• metalloid

Which group of elements has, in general, higher melting and boiling points?

• metals

• nonmetals

What would be a good element to make an electrical wire out of?

• Copper because it is a metal and conducts electricity well.

• Carbon because it is a solid at room temperature.

• Hydrogen because it is a nonmetal and conducts electricity well.

What is luster?

• The way a surface reflects light

• The way a substance can be shaped by hammering

• The way a substance conducts electricity.
